A wheel rolls purely on ground. Find a point on the periphery of a body which has a velocity equal to the velocity of the centre of mass of the body.

A wheel rolls purely on ground. Find a point on the periphery of a body which has a velocity equal in magnitude to the velocity of the centre of mass of the body.

In pure rolling velocity of center of mass is equal to

The escape velocity of a body does not depend on the mass of the body.

A wheel is rolling without slipping on a horizontal surface. In an inertial frame of reference in which the surface is at rest, is the reanypoint on the wheel that has a velocity that is purely vertical ? Is there any point that has a horizontal velocity component opposite to the velocity of the centre of mass ? Explain. What would be the results if wheel is slipping with rolling ?

A body of mass 20 kg is moving with a velocity of 2v and another body of mass 10 kg is moving with velocity V along same direction. The velocity of their centre of mass is

If the velocity of centre of mass of a rolling body is V then velocity of highest point of that body is

In pure rolling, the velocity at the point of contact:
