The graph shows the speed of a car travelling through a town. Which section of the graph represents a period when the car is decelerating?

A student measures the average speed of a cyclist in a race. Which quantities must she measure?

• the total time taken to complete the race and the time taken for the cyclist to reach her highest speed

• the total time taken to complete the race and the total distance travelled by the cyclist at her highest speed

• the total time taken to complete the race and the total distance travelled by the cyclist

• the time taken to reach her highest speed and the total distance travelled by the cyclist

The graph shows the motion of a sprinter.

She accelerates steadily from rest to 8.0 m/s in 4.0 s.

How far does she travel in the last three seconds of her acceleration?

• 9.0 m

• 15 m

• 16 m

A train is on a straight track.

The graph shows how a quantity y varies with time.

1 The train is stationary and y represents the distance from the last station.

2 The train is moving and y represent the distance from the last station.

3 The train is stationary and y represent the speed of the train.

4 The train is moving and y represent the speed of the train.

• 1 and 2

• 1 and 4

• 2 and 3

• 3 and 4
