1A long-distance runner wishes to calculate her average speed for a race.
Which calculation should she use?- Aaverage speed = total distance / total time
- Baverage speed = total distance × total time
- Caverage speed = total time / total distance
- Daverage speed = total distance + total time
2A heavy metal ball falls vertically downwards through air past four equally spaced levels J, K, L and M.

- Aspeed is greatest between J and K: time is shortest between J and K
- Bspeed is greatest between J and K: time is shortest between L and M
- Cspeed is greatest between L and M; time is shortest between J and K
- Dspeed is greatest between L and M; time is shortest between L and M
3A ball is rolling down one hill and up another. Points A and B are at the same height on the two different hills . How do the velocity and acceleration change as the ball rolls from point A to point B?
- AThe velocity and acceleration are the same at both points.
- BThe velocity and the magnitude of the acceleration are the same at both points, but the direction of the acceleration is opposite at B to the direction it had at A.
- CThe horizontal component of the velocity is the same at points A and B, but the vertical component of the velocity has the same magnitude, but the opposite sign at B. The acceleration at points A and B are the same.
- DThe vertical component of the velocity is the same at points A and B, but the horizontal component of the velocity has the same magnitude, but the opposite sign at B. The acceleration at points A and B has the same magnitude, but opposite direction.
4The graph shows how the acceleration of an object moving in a straight line varies with time.
Which graph shows the variation with time of the velocity of the object?
- AA
- BB

- CC

- DD

- AA
5A ball is released from rest at time zero. After 1.0 s it bounces inelastically from a horizontal
surface and rebounds, reaching the top of its first bounce after 1.5s.
What is the total displacement of the ball from its original position after 1.5s?
- AA 1.25 m
- BB 3.75 m
- CC 5.00 m
- DD 6.25 m
