The displacement of a runner at various instants is given below:
t (s): 0 2 5 7 10
x (m): −2 5 5 −4 1
(a) Calculate the average velocity for each of the following intervals:
(i) 0 s – 2 s,
(ii) 2 s – 5 s,
(iii) 5 s – 7 s,
(iv) 7 s – 10 s.
(b) During which interval is the magnitude of velocity greatest? State that value with its sign.
