In the figure the block B of mass m starts from rest at the toop of a wedge W of mass M A surfaces are without firction W can slide on the ground B slides down on to the ground moves along it with a speed V has an elastic collision with the wall and climbs back on to W a from the beginnning till the collision with the wall the centre of mass of B plus W does not move horizontally b After the collision the centre of mass of B plus W moves with the velocity 2mV m M c When B reaches its highest position of W the speed of W is d When B reaches its highest position of W the speed of W is 2mV m M mV m M B m W M
