The velocity-time graph shows the motion...

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.

Text Solution

Verified by Experts

As velocity time graph is a straight line parallel to the time axis, therefore, its velocity = constant.
(i) acceleration of cyclist, `a = 0`
(ii) In `t = 15 s, v = 20 m//s`, from the graph
(iii) In `t = 15 s`, distance covered, `s = v xx t = 20 xx 15 = 300 m`.
