At any instant, a rolling body may be considered to be in pure rotation about an axis through the point of contact. This axis is translating forward with speed

View answer and explanation

Correct option: A

Equal to speed of centre of mass

Option A is correct because, in pure rolling, the instantaneous axis of rotation is at the point of contact, and this axis translates forward with the same speed as the center of mass.
