You have an old style reel lawn mower at home. No engine! You need to cut the grass but also finish in time to watch your favorite Tv show. How would you apply Newton’s second law of motion here?
Answer:
the force on an object is equal to its mass times its acceleration.
Explanation:
the more heavier the object (lawn mower) the more time it will take to cut the grass due to that the tv show will be gone
The mass of the old-style reel lawn mower will be large, it will take to too much time to cut the grass as the acceleration of the lawn mower will be less.
What is Newton's second law of motion?According to Newton’s second law of motion, the force equals mass times acceleration for a constant mass.
This states that the acceleration of an object depends on two variables. The first one is the mass of the object and the net force acting on the object. The acceleration is directly proportional to the net force acting on the body and inversely proportional to the mass.
The expression of Newton’s second law can be written as follows:
F = ma or a = F/m
The expression shows that the direction of the acceleration vector is the same direction as the net force vector.
The acceleration of the mower will be inversely proportional to the mass of the lawn mower. The larger the mass of the mower, the smaller the acceleration produced by a given force in the mower.
Therefore, an old-style reel lawn mower will take more time to cut the grass.

A projectile is fired vertically upwards and reaches a height of 78.4 m. Find the velocity of projection and the time it takes to reach its highest point.
Answer:
1.) U = 39.2 m/s
2.) t = 4 seconds
Explanation: Given that the
height H = 78.4m
The projectile is fired vertically upwards under the acceleration due to gravity g = 9.8 m/s^2
Let's assume that the maximum height = 78.4m. And at maximum height, final velocity V = 0
Velocity of projections can be achieved by using the formula
V^2 = U^2 - 2gH
g will be negative as the object is moving against the gravity
0 = U^2 - 2 × 9.8 × 78.4
U^2 = 1536.64
U = sqrt( 1536.64 )
U = 39.2 m/s
The time it takes to reach its highest point can be calculated by using the formula;
V = U - gt
Where V = 0
Substitute U and t into the formula
0 = 39.2 - 9.8 × t
9.8t = 39.2
t = 39.2/9.8
t = 4 seconds.

You pull a force of 255 N on a piece of luggage of mass 68 kg but does not move the coefficient of friction between the luggage in the floor is .7 what is the force of static friction acting on the luggage
Answer: 255N
Explanation:
Given the following :
Applied force (F) = 255N
Mass (M) of the body = 68kg
Coefficient of static friction (Us) = 0.7
Recall:
Us = frictional force / normal reaction(N)
Normal reaction( N) = mass × acceleration due to gravity
N = mg = 68 × 9.8m/s^2 = 666.4N
Therefore,
Frictional force = coefficient of static friction × normal reaction
Frictional force = 0.7 × 666.4 = 466.5N.
In other for the body to move, the minimum applied force must be greater than the frictional force in other to overcome the force of friction.
Here, the force applied on the object is equal to the force of static friction which is less than the frictional force.
255N = force of static friction.
Answer: 255N

The woman was standing on a cliff 30 meters above where she landed. There was a safety fence 4 meters from the cliff edge that would have prevented her from taking a long distance to run and leap off the cliff. She landed 12 meters away from the base of the cliff. Her launch speed was calculated to be 4.86 m/s, meaning that to travel those 12 meters, she had to be traveling at 10.87 miles per hour (or moving faster than a runner at a 5.5 minute mile pace) as she left the cliff. Put all this information together. Why did forensic scientists determine that the woman’s body was thrown instead of concluding that she jumped off the cliff?
Answer:
Forensic scientists determined that the woman’s body was thrown off the cliff because after considering the velocity and angle of the projectile needed in relationship to the cliff she could not have reached those speeds and cleared the safety fence 4m away from the cliff’s edge. She would have been going faster than a 5.5 minute mile pace and she was not an athletic person.
** Just make sure to change the format and/or wording. Hope I was helpful :-)
The woman’s body was thrown instead of concluding that she jumped off the cliff as there has more initial speed than regular which is provided during throw.
What is projectile motion?When a particle is hurled obliquely near the surface of the earth, it travels along a curved path while accelerating continuously in the direction of the planet's center (we assume the particle stays close to the surface of the globe). Such a particle's motion is known as projectile motion, and its route is referred to as a projectile.
Given: She landed 12 meters from the cliff's base.
And when she jumped off the cliff, her estimated launch speed was 10.87 miles per hour. She could have avoided having to go a considerable distance in order to jump over the cliff by using the safety barrier that was 4 meters away.
Hence, Instead of drawing the conclusion that the woman leaped from the cliff, the body of the woman was flung since throwing provides more initial speed than usual.

Answer: 80
Explanation:
The question is incomplete, There is no specific time for the specific velocity, which is not provided in this question instead of giving the total time interval from 0sec to 80 sec. According to my assumption, I think the net displacement will be 20 m. The correct answer will be option D.
What is net displacement?Net displacement is the total change in the position of an object, taking into account both the magnitude and direction of its motion. It is a vector quantity and is expressed in terms of distance and direction.
In other words, it is the final position of an object relative to its initial position, irrespective of the path taken. It is calculated by finding the vector difference between the final and initial positions of the object.
For example, if an object moves 10 meters to the east and then 5 meters to the north of its starting position, then its net displacement would be the vector sum of these two displacements, which is the diagonal distance between its starting and final positions.
Here in the Question,
To calculate the net displacement of the particle between 0 seconds and 80 seconds based on the given options, we can use the fact that the net displacement is the same as the final position minus the initial position.
Let's assume that the initial position is zero.
Option A. If the net displacement is 160 meters, the final position would be 160 meters. However, looking at the velocities given, we can see that the particle goes back and forth, so it does not make sense for the net displacement to be larger than the maximum displacement in one direction.
Option B. If the net displacement is 80 meters, the final position would be 80 meters. This option could be possible if the particle moves in one direction for a while and then moves back to its initial position. This is incorrect.
Option C. If the net displacement is 40 meters, the final position would be 40 meters. This option is also possible if the particle moves in one direction for a shorter period of time. This is not relevant to the question.
Option D. If the net displacement is 20 meters, the final position would be 20 meters. This option could be possible if the particle moves in one direction for a very short period of time. This is most relevant to the Question.
Option E. If the net displacement is 0 meters, the final position would be the same as the initial position, which is zero. This option could be possible if the particle moves back and forth such that the positive displacements cancel out the negative displacements.
Therefore, based on the given options, the correct answer for the net displacement of the particle between 0 seconds and 80 seconds is option D: 20 meters.

Hz. What is Rigel's velocity relative
to us?
PLS HELP!
Answer: V = 4.35 × 10^12 m/s
Explanation: To calculate Rigel velocity relative to us, we should use doppler effect formula.
Fo = (c ) / ( c - Vs) × f
Fo/f = (c ) / ( c - Vs)
4.26 × 10^10 = (3×10^8) 6.17×10^14/(3×10^8 - V)
4.26×10^10/6.17×10^14 = (3×10^8)/(3×10^8 - V)
6.9×10^-5 = (3×10^8)/(3×10^8 - V)
Cross multiply
20713.13 - 6.9×10^-5V = 3×10^8
Collect the like terms
6.9×10^-5V = 3×10^8 - 20713.13
6.9×10^-5V = 299979286.9
V = 299979286.9/6.9×10^-5
V = 4.3475 × 10^12 m/s

How much momentum will a dumbbell of mass 10kg transfer to the floor if it falls from a height of 80cm (assume that the dumbbell stops after hitting the ground) ? Take g=10m/s^2
(Point stealers will be reported so better dont do it)
Answer: momentum = 40kgm/s
Explanation:
Given that the
Mass M = 10kg
Height H = 80 cm = 0.8m
g = 10m/s^2
The velocity of the dumbbell as it fall can be calculated by using the formula;
V^2 = U^2 + 2gH
Since the dumbbell fell from rest, initial velocity U = 0
Substitute g and H to get final velocity V
V^2 = 0 + 2 × 10 × 0.8
V^2 = 16
V = sqrt(16)
V = 4 m/s
Momentum is the product of mass and velocity. That is,
Momentum = MV
Substitute mass M and V into the formula
Momentum = 10 × 4 = 40kgm/s
Therefore, 40 kgm/s momentum will be transferred as the dumbbell fall to the floor.
A 14 kilogram beam is hinged at one end. A 6.0-kilogram triangular object and a 7.5-kilogram capital I-shaped object are placed as shown in the figure. The dots indicate the individual centers of gravity of the beam and objects. The center of mass of the entire system must be:
Answer: 1.3 m
Explanation:
From the figure attached, 3 materials are involved. A 14 kilogram beam hinged at one end, a 6.0-kilogram triangular object and a 7.5-kilogram capital I-shaped object.
Let take the moment at the hinge axis.
The moment for the beam will be
14 × ( 0.36 + 0.53 ) = 12.6
The moment of the triangle object will be 6 × 0.36 = 2.16
The moment of capital I shape will be
7.5 × ( 0.36 + 0.53 + 1.92 ) = 21.075
The total moment = 12.6 + 2.16 + 21.075
The total moment = 35.835
The total mass = 14 + 6 + 7.5 = 27.5
The center of mass of the entire system must be:
X = total moment ÷ total mass
Substitute both in the formula
X = 35.835/27.5
X = 1.3 m.
Therefore, The center of mass of the entire system must be 1.3m
