Question 17
The velocity-time graph shows the motion of a cyclist. Find (i) its acceleration (ii) its velocity and (iii) the distance covered by the cyclist in 15 seconds.

Answer 1

(i) Since velocity is not changing, acceleration is equal to zero.
(ii) Reading the graph, velocity = $20m{s}^{-1}$
(iii) Distance covered in 15 seconds, $s=u\times t=20\times 15=300m$
