Question

15. The following velocity - time graph shows the motion of a cyclist. Find (1) it's
acceleration (ii) the velocity and (iii) the distance covered by the cyclist in 15
seconds.
​

Answer 1

(a)Since velocity is not changing, acceleration is equal to zero.

(b) Reading the graph, velocity=20ms

−1

(c) s = area of the figure enclosed under v-t graph. Distance covered in 15s, s=ut=20×15=300m
