The diagram shows the positions of a ball as it rolled down a track. The ball took 0.5 s to roll from one position to the next. For example, it rolled from A to B in 0.5 s and from B to C in 0.5 s and so on.

a. Write down:

i. The distance travelled by the ball from A to E;

ii. The time taken by the ball to reach E. 

b. Calculate the average speed of the ball in rolling from A to E. Write down the formula that you use and show your working. 

c. Explain: 

i. How you can tell from the diagram that the ball is speeding up; 

ii. Why the ball speeds up.
