Use the principle of conservation of mechanical energy to find the speed of the block at the base of the incline.

Use the principle of conservation of mechanical energy to find the speed of the block at the base of the incline. (carry the answer to one decimal)There is a picture with a block of mass, M on a inclined plane, the height at the top of the plane is .60 m. Then is shows that the block slides down the incline onto a horizontal plane. How do i find its speed at that moment? Thanks.
