Question
A hollow sphere is released from the top of a wedge as shown in the figure. There is no friction between the wedge and the ground. There is sufficient friction to provide pure rolling of the sphere. The velocity of the sphere with respect to ground just before it leaves the wedge will be [Assume masses of the wedge and sphere are equal, h>>R the radius of sphere and the portion of wedge where the sphere leaves the wedge is horizontal]
The correct answer is:
