End of chapter tests: 01 Kinematics

1 Cars X and Y start from the same place. They are both travelling to a destination 480 km away.

Car X starts at time 0 and travels at a speed of 60 km h-1.

Car Y starts one hour later and travels at a speed of 80 km h-1

Which car gets to the destination first, and what is the time between the arrivals of the two cars at the destination?

2 The initial velocity of a body is 6.0 m s-1

The graph shows the variation with time of the acceleration of the body.

What is the velocity at t = 3 s?

9.0 m s-1

15 m s-1

18 m s-1 24 m s-1

3 The initial position of a body is 8.0 m. The graph shows the variation with time of the velocity of the body.

What is the position at t = 6 s?

4 A stone is thrown vertically upwards with speed 20 m s-1. How high does it get?

5 A stone is thrown vertically downwards from the edge of cliff on a planet without an atmosphere at t = 0.

At t = 1 s, the stone’s speed is 11 m s-1, and at t = 3 s it is 23 m s-1.

What is the initial speed of the stone, and what is the acceleration of free fall on the planet?

Initial speed (m s-1) Acceleration of free fall (m s-2)

6 The velocity of an object varies with time as shown in the graph.

Which graph shows the variation with time of the acceleration of the object?

7 Three statements are made for projectile motion in the presence of air resistance. The statements compare this motion to that without air resistance.

I The horizontal distance travelled is less.

II The maximum height reached is less

III The impact angle is steeper.

Which are correct?

I and II

I and II

II and III

I, II and III

8 Two projectiles are launched horizontally on two different planets. The diagram shows the positions of the projectiles every 0.5 s.

What can be concluded about the launch speed and the acceleration of free fall on the two planets?

Horizontal speed Acceleration of free fall

A same same

B same different

C different same

D different different horizontal distance travelled by X horizontal distance travelled by Y

9 The diagram shows the position, every 0.40 s, of a projectile launched horizontally on a planet.

What is the launch speed, and what is the acceleration of free fall on the planet?

10 Two projectiles, X and Y, are launched horizontally with the same speed. X is launched from a height 4h and Y from a height h.

What is when both land on the ground?
