Question

a man is moving with uniform speed(20m/s) ,along how much time he will complete his first round, second round & third round, starting from rest. suppose he completes his round in 'T' seconds, then what will be distance covered as well as displacement in T/2 seconds?

Answer 1

The speed of the man, v = 20m/s

If the radius of the circle is r, then time taken = 2?r/v s

Since the man is moving at uniform speed, he will cover each round in the same time.

Distance covered by man in T/2 = vT/2 m

Displacement covered by the man in T/2 = 2r = vT/2
