Question

The velocity-time graph shows the motion of a cyclist. Find
(i) its acceleration
(ii) its velocity
(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
