Question

In the figure, a small solid uniform ball is to be shot from a point P so that it rolls smoothly along a horizontal path, up along a ramp, and onto a plateau. Then it leaves the plateau horizontally to land on a game board, at a horizontal distance d from the rigth edge of the plateau. The vertical heights are h_{1}= 5.00cm and h_{2}=1.60cm

a) With what speed must the ball leave the plateau for it to land at d=6.00cm

b) What fraction of the ball's kinetic energy is rotational while it is on the plateau?

c) With what speed must the ball be shot at point P for it to land at d=6.00cm?
