Question

A solid ball of mass m and radius R is given linear velocity V and no angular velocity and placed on a rough surface.What is the velocity of the centre of mass when ball starts pure rolling.

Answer 1

hello Friend....☺
Your answer is zero because in rotatory motion the center of mass is considered at rest...

Answer 2

$heya....$

in rotatory motion the centre of mass is considered to be at rest so the body is at rest.
so rest is the answer.
