A hollow sphere of radius r is rotating ...

A hollow sphere of radius r is rotating about a horizontal axis at some angular speed `omega_(0)`. It is gently lowered to ground and the coefficient of friction between sphere and the ground is `mu`.How far does the sphere move before it starts pure rolling?

Text Solution

Verified by Experts

The correct Answer is:
`[(2)/(25)(omega_(0)^(2)r^(2))/(mug)]`
