Question

The velocity-time graph (Fig. 8.5) 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 = 20 m s^-1 

(iii) Distance covered in 15 seconds, s = u ×t = 20 × 15 = 300 m
