Question

What is the speed of an athlete moving along a circular path of radius r

Answer 1

Answer:

An athlete is moving along a circular path of radius R and he takes t seconds to go around the circular path once

Answer 2

Hey Mate, this is your answer

Firstly, the athlete is moving around a circular path. ( Main part to keep in mind before solving).

Speed = Distance/Time

Here, DISTANCE = 2PR ( P respresents pie).

TIME= t (say)

Therefore, speed of athlete around a circular path = 2PR/t
