A car’s brakes decelerate it at a rate of -1.70 m/s2. What is the time, in seconds, required to slow the car from 15 m/s to 9.0 m/s?
Answer:
t = 3.52 s
Explanation:
Given that,
The deceleration of a car is, a = -1.7 m/s²
The initial velocity of the car, u = 15 m/s
Final velocity of the car, v = 9 m/s
We need to find the time that is required to slow the car from 15 m/s to 9 m/s. The definition of acceleration is :
[tex]a=\dfrac{v-u}{t}\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{9-15}{-1.7}\\\\t=3.52\ s[/tex]
So, it will take 3.52 seconds to slow the car from 15 m/s to 9 m/s.
Calculate the total energy transferred when 200 g of ice cubes at 0°C are changed to steam at 100°C.
Specific heat capacity of water = 4200 J/kg °C
Specific latent heat of fusion = 340 kJ/kg
Specific latent heat of vaporisation = 2260 kJ/kg
Answer:
[tex]604000\ \text{J}[/tex]
Explanation:
m = Mass of ice = 200 g
[tex]\Delta T[/tex] = Temperature change of water = [tex](100-0)^{\circ}\text{C}[/tex]
c = Specific heat capacity of water = 4200 J/kg °C
[tex]L_f[/tex] = Specific latent heat of fusion = 340 kJ/kg
[tex]L_v[/tex] = Specific latent heat of vaporisation = 2260 kJ/kg
Heat required to convert ice to water = [tex]mL_f[/tex]
Heat required to raise the temperature of water to boiling point = [tex]mc\Delta T[/tex]
Heat required to convert water to steam = [tex]mL_v[/tex]
Total heat required
[tex]q=mL_f+mc\Delta T+mL_v\\\Rightarrow q=m(L_f+c\Delta T+L_v)\\\Rightarrow q=0.2(340\times 10^3+4200(100-0)+2260\times 10^3)\\\Rightarrow q=604000\ \text{J}[/tex]
Heat required to convert the given amount of ice to steam at the required temperature is [tex]604000\ \text{J}[/tex].

Objects with different masses have the same gravitational force acting
on them.
TRUE
FALSE
True or false? When a change of state starts to occur, the energy supplied changes the temperature but not the internal energy.
Answer:
True
Explanation:
This heat energy allows the change of state to happen, and the temperature remains constant during the process. The amount of energy required to change the state of a substance depends upon the mass and characteristics of that substance. The energy required to change the state of a material is known as the latent heat. During a change of phase the temperature does not change, but the internal energy does. The internal energy is the sum of the kinetic energy of the molecules and the chemical potential energy of the molecules.

At night, within how many feet of approaching a vehicle from the rear must you dim your high beam headlights
Answer: 500 ft
Explanation:
High beam headlights help one to see better at night as the range of vision is greatly expanded. They can however, blind drivers coming on the opposite lane.
It is therefore prudent to ensure that when using high beam headlights, you dim them when a car is coming towards you. The appropriate distance to do so is a minimum of 500 ft from the car.

What are the units of Mass and Weight in the English System? Explain.
Answer:
I tried...
Explanation:
Assuming the English system of mass and weight is the same as the Imperial system, the measurements are:
• 1 pound (lb) = 16 ounces (oz)
• 2,000 pounds (lbs) = 1 ton (T)
I think that's everything?
In the English system, mass is measured in pounds and weight is also measured in pounds. However, it is important to understand the difference between mass and weight.
Mass is a measure of the amount of matter in an object and is a scalar quantity. It does not change with location or gravitational force. In the English system, mass is typically measured using a scale or balance, which compares the object's mass to a standard mass. The pound (lb.) is the unit of mass in the English system.
Weight, on the other hand, is a measure of the force exerted on an object due to gravity and is a vector quantity. It depends on the object's mass and the gravitational force acting on it. In the English system, weight is typically measured using a spring scale or a balance that incorporates a spring. The pound (lb.) is also used as the unit of weight in the English system.
Weight = Mass x Acceleration due to gravity
Mass is measured in pounds (lb.) and weight is also measured in pounds (lb.).It is important to note that weight can vary depending on the gravitational force acting on an object.

help pls physics problem
Answer:
0.4329 seconds
Explanation:
We are given;
Distance; d = 0.635 m
Velocity; v = 3.22 m/s
Angle; θ = 62.9°
To find the time, we have to find the horizontal component of the velocity.
Thus, Vx = 3.22 × cos 62.9
Formula for time is;
t = d/Vx
t = 0.635/(3.22 × cos 62.9)
t = 0.4329 sec
Thus the time he will take to clear the hurdle is 0.4329 sec

A 15-kilogram wagon originally at rest on a level road is pulled by a rope that exerts a constant horizontal force of 45 newton's, If the frictional forces on the wagon total 15 newton's, what will be its acceleration ? *
2.0 〖m/s〗^2
4.0 〖m/s〗^2
15 〖m/s〗^2
30 〖m/s〗^2
3.0 〖m/s〗^2
Answer:
A. 2 m/[tex]s^{2}[/tex]
Explanation:
Mass of wagon = 15 kg
Horizontal force = 45 N
frictional force = 15 N
It is good to note that part of the exerted horizontal force would be used to overcome the frictional force on the wagon.
So that, total force exerted on the wagon can be determined by;
total force = horizontal force - frictional force
= 45 - 15
= 30 N
From Newton's second law of motion, we have;
F = ma
Where: F is the force applied on an object, m is its mass, and a is the acceleration of the object.
Thus,
30 = 15 x a
a = [tex]\frac{30}{15}[/tex]
= 2 m/[tex]s^{2}[/tex]
The acceleration of the wagon is 2 m/[tex]s^{2}[/tex].

A truck is traveling at constant speed of t v =21 m/s is at x= (80, 100, 120, 140, 160) m in front of a police car moving with constant speed of p v =25 m/s. What is the time (in s) needs the police to catch the truck?
Answer:
t= (20, 25, ... 40) s
Explanation:
This is an exercise in kinematics specifically of uniform motion, the first thing we must do is set a reference system, we place our zero in the police car, we write the equations
police car
x₁ = v₁ t
truck
x₂ = x₀ + v₂ t
In this case, they indicate several initial positions of the truck and the speed of the two vehicles, at the meeting point the positions must be the same
x₁ = x₂
v₁ t = x₀ + v₂ t
t (v₁ - v₂) = x₀
t = [tex]\frac{x_{o} }{v_{1}- v_{2} }[/tex]
let's calculate for each initial position
x₀ = 80m
t = 80 / (25-21)
t = 80/4
t = 20 s
x₀ = 100 m
t = 100/4
t = 25 s
the last x₀ = 160 m
t = 160/4
t = 40 s
we can see that the time increases as the distance between the vehicles increases

A clock which has brass pendulum beats correctly at 30C will it run faster or slower if temperature increase or decrease
Answer:
We know that the period of a pendulum is written as:
T = 2*pi*√(L/g)
where:
g = gravitational acceleration = 9.8m/s^2
pi = 3.1415...
L = length of the pendulum, in this case, is the length of the brass pendulum.
Now, we know that the brass dilates when the temperature increases.
Then if the temperature increases, the value of L will increase, which means that the period T will also increase, because L is in the numerator of T.
If the period increases the complete motion of the pendulum needs more time, this would mean that the clock will run slower.
If the temperature decreases, the opposite occurs, the value of L decreases, and then the period also decreases, which means that the clock will run faster.
