In the figure shown, a uniform solid cylinder A is initially rolling with velocity 14 m/s on the horizontal surface of wedge B of identical mass. All surfaces are smooth and B has no initial velocity. Find maximum height (in m) reached by cylinder. ( $g = 9.8 m / s^{2}$ )

The cylinder spin is unchanged because all surfaces are smooth. Conserve horizontal momentum and translational energy available for climbing. This gives h=5 m.
