Question

Find the expression for the speed of an athlete performing UCM of a circular track of radius ‘r’ in time period ‘t’.
Thank you

Answer 1

Answer:

If a body is moving in a circular orbit of radius r and the body covers a distance equal to the circumference of that circle d=2πr

This amount of distance is covered in time T.

So, the speed of a body in uniform circular motion is

s=

2πr

_____

T
