Question

A cyclist moving on a circular track of radius 40 metre completes half a revolution in 40 seconds find his average velocity

Answer 1

v=average velocity

s=distance

t=time

v=s/t

v=40/40

v=1

Answer 2

Answer:

total displacement =2R

total time =40 sec

average velocity =total displacement /total time

Vav=2×40/40

V=2 m/s
