The following table shows the velocity of a cyclist moving along a straight track:
Time t (s): 0 2 4 6 8 10
Velocity v (m s−1): 0 4 8 12 16 21
(i) For each successive 2-s interval calculate the average acceleration.
(ii) State whether the cyclist’s motion is uniformly accelerated over the whole 10 s. Justify your answer with the values obtained in part (i).
