Explanation:
To be able to solve this type of problems it is always advisable to make a free body diagram with the forces acting on the body.
Attached is an image with the free body diagram and the proposed equations, the explanation of obtaining the equations will be described below.
Let's take the movement to the left as positive, i.e. all forces going to the left have a positive sign.
Let's use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
To the left we have the two forces of tension by the cosine of the angle. And to the right the frictional force. The resultant of these forces is equal to the product of the mass (mass of the child plus the mass of the sled), by acceleration.

Based on illustrations of magnetic field lines, where could an object be placed so it would not experience a magnetic force?
halfway between the like poles of two magnets, because the field lines bend away and do not enter this area
halfway between the opposite poles of two magnets, because the field lines are the closest together
above the middle of a bar magnet, because the magnetic field lines are only found around the sides of the magnet
above a pole of a bar magnet, because the magnetic field lines either go in or go out at the end
Answer:
(a) halfway between the like poles of two magnets, because the field lines bend away and do not enter this area

Explanation:?
You travel 50 meters at an angle of 37° North of East.
a) Calculate the Horizontal component.
Answer:
a) x = 39.9 m
Explanation:
To find the components of a vector we can use trigonometric relationships. Since they indicate that the angle is 37º north of east, this angle is measured counterclockwise from the x-axis, therefore using trigonometry.
cos θ = x / d
sin θ = y / d
where the angle is 37º and the distance d = 50 m
x = d cos θ
y = d sim θ
let's calculate
x = 50 cos 37
y = 50 sin 37
x = 39.9 m
y = 30.1 m
BMW has introduced a program of covered scheduled maintenance for its cars. That is, when you bring in your vehicle for maintenance at a BMW dealership, BMW will cover the costs of everything (except for worn-out tires). This practice specifically targets which stage of the product life cycle?
Answer:
Usage
Explanation:
A product life cycle refers to the duration from the introduction of the product into the market until it's taken off the shelves.
A program of covered scheduled maintenance for the cars refers to the practice in which the dealership will cover the costs of everything when you bring in your vehicle for maintenance.
In this question, the mentioned practice specifically targets the stage - Usage of the product life cycle
A helicopter takes off from the ground and rises vertically. It then hovers at a constant height above the ground. Which sequence of energy changes takes place during the gain in height?
Answer:
First the fuel in the engine gives chemical energy during burning. That chemical energy then converts to kinetic energy if the rotor of blades of the helicopter. Then kinetic energy converts in gravitational potential energy as it gains height.

What is the displacement of a soccer player who moves from 20 yards to 65 yards down the field?
Answer:
All that is necessary is that car A has a greater speed (is moving faster). ... A fullback is running down the football field in a straight line. ... At 1 second, he is on the 10-yard line; at 2 seconds, he is on the 20-yard line; at 3 seconds, he is on ... Since average velocity is displacement over time, his average velocity is also 0 m/s.
Explanation:
Answer:
45 yards of displacement from the 20 yard point
Explanation:
take the 65 and subtract 20 from it and that will give you your displacement.
Using our knowledge of physics... If we know that the moving man travels 10 meters, has an initial velocity of 0 m/s and an acceleration of 1 m/s, use the equation d = vi t + 1/2 a t^2 to solve for time.
Answer:
t= 4.5s
Explanation:
vi=0m/s
a= 1m/s
d=10m
10m= 0(t) + 1/2(1m/s)(t^2). 0xt cancels out, 1/2 of 1= .5
10m= .5m/s(t^2) Divide both sides by .5
20m= t^2. Take square root of each side
Square root of 20 is 4.472135954999579
sig figs, t= 4.5 s
A biker starts moving from rest with a constant acceleration of 2.0 m/s^2. What is his velocity after 5.0 s?

An object launched at 65 degrees from the horizontal would have the same range
(distance travelled) as an object launched from? Write only the WHOLE number with
no units (example: 65)
Answer:
An object launched from 65° will have the same range as an object launched from 25°
Explanation:
The formula for the horizontal range, R, is given as follows;
[tex]R = \dfrac{v \times sin(2\cdot \theta)}{g}[/tex]
Therefore, given that sinθ increases from 0 to 1 for θ values from 0 to 90° and decreases from 1 to 0 for θ values from 90° to 180°, and that the values of sin(θ) are positive in the first and second quadrant, we have that for the given angle, θ = 65°, the range is therefore;
[tex]R = \dfrac{v \times sin(2\times 65 ^{\circ})}{g} = \dfrac{v \times sin(130 ^{\circ})}{g}[/tex]
The location of 130° = Second quadrant
A rotation of 130° in the counterclockwise is equivalent to a rotation of 50° in the clockwise direction
Therefore, we have sin(130°) = sin(50°)
Therefore, the range for 130°/2 = 65° is the same as the range for 50°/2 = 25° and an object launched from 65° will have the same range as an object launched from 25°.

A bullet is fired at an angle of 45°. Neglecting air resistance, what is the direction of acceleration during the flight of the bullet?
a) upward
b) downward
c) dependent on the initial velocity
d) at a 45 angle
Answer:
b) downward. Correct choice
Explanation:
Projectile Motion
It's known as the type of motion that experiences an object that is projected near the Earth's surface and moves along a curved path exclusively under the action of gravity.
The gravity manifests through the acceleration of gravity g whose value is [tex]9.8 m/s^2[/tex] and points downward. The object will eventually fall to the ground at a time and speed which depends on the initial speed and launch angle.
When the bullet is fired regardless of the initial speed and angle, the only acceleration of the system is g, thus:
b) downward. Correct choice
The acceleration acts on the bullet will be the acceleration due to gravity that is g and has a downward direction.
What will be the direction of the acceleration of Bullet fired?Since the bullet is fired at an angle of 45 so the bullet will travel in a projectile. So every point in time the acceleration due to gravity will act on the bullet.
After some point in time, the bullet will come to the surface of the earth as the energy in the bullet will reduce.
As we know that anything present on the earth is under the influence of the earth's gravity.
So the fired bullet will experience acceleration due to the gravity of the earth and the direction of the acceleration will always be downwards.
So the bullet will eventually fall to the ground at a time and speed which depends on the initial speed and launch angle.
Thus the acceleration acts on the bullet will be the acceleration due to gravity that is g and has a downward direction.

Samuel's car has a mass of 3,000 kg. If your car produces a force of 500 N, how fast will it accelerate?
Answer:
The answer is 0.17 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex] a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass
From the question we have
[tex]a = \frac{500}{3000} = \frac{5}{30 } = \frac{1}{6} \\ = 0.166666...[/tex]
We have the final answer as
0.17 m/s²Hope this helps you
