Question

An object is moving on a circular path of radius $\pi$ meters at a constant speed of $4.0m/s$. The time required for one revolution is:

Answer 1

Given, $Radius=\pi ,Speed=4.0m/s$

We know that,

Velocity $V=\frac{d}{t}$

$t=\frac{d}{V}=\frac{2\pi R}{V}=\frac{2{\pi }^2}{4}=\frac{{\pi }^2}{2}=4.9s$
