Question

An athlete take second to complete one round of a circular track of radius 'r' then its velocity circular motion
A)= 2πr/t
B)=2πrt
C)=1/2πrt
D)=πr/2t​

Answer 1

Answer:

A)= 2πr/t

Explanation:

tthe answer is 2πr/t because

speed =distance/time

therefore,

distance=2πr

time = t

hence, speed=2πr/t
