Question

A boy moves in a circular path of radius 20 m He moves one complete circle and stops. Find total distance and net displacement.

Answer 1

Answer:

Distance covered by boy = 125.6 m

Displacement is zero.

Explanation:

Total distance covered by the boy = 2 π r

r = 20m

D = 2 x 3.14 x 20 = 125.6 m

Displacement is zero since the boy returns to the initial point.
