A cyclist is travelling at 15 m s^-1. She applies brakes so that she does not collide with a wall 18 m away. What deceleration must she have?

A cheetah starts from rest, and accelerates at 2 m/s² for 10 seconds. Calculate :

(a) the final velocity

(b) the distance travelled.

A train travelling at 20 m s^-1 accelerates at 0.5 m s^-2 for 30 s. How far will it travel in this time?

Draw a velocity-time graph to show the following motion :

A car accelerates uniformly from rest for 5 s; then it travels at a steady velocity for 5 s.

The velocity-time graph for part of a train journey is a horizontal straight line. What does this tell you about

(a) the train’s velocity, and

(b) about its acceleration?
