= A small block of mass m 0.795 kg is released from rest at the top of a curved wedge of mass m2 = 6.50 kg, which sits on a frictionless horizontal surface as in figure (a). When the block leaves the wedge, its velocity is measured to be 4.00 m/s to the right, as in figure (b). h a mi M2 4.00 m/s m2 m b i (a) What is the velocity of the wedge after the block reaches the horizontal surface? (Enter the magnitude of the velocity.) m/s (b) What is the height h of the wedge? m Need Help? Read It
