Question

A cylinder of mass m and a block of wood of mass m are both released from rest at a height h on an inclined plane at the same time. The cylinder rolls down the plane without slipping due to friction. The block slides down the incline. If they both experience the same frictional force, which has more total kinetic energy when they reach the bottom?
A. The cylinder
B. The block
C. they have the same total kinetic energy when they reach the bottom
D. there is not enough information to answer this question

Answer 1

Answer:

A

Explanation:

Because in block friction does not work hence case of cylinder has more total K.E
