a small block of mass M=0.050 kg is released from rest at the top (h=0.60 m) of the curved frictionless ramp shown above. The block slides down the ramp and collides with a larger block of mass 1.5M=0.075 kg at rest at the bottom of the incline. The larger block moves to the right at a speed 2.0 m/s immediately after the collision. Determine the speed of the small block immediately before the collision.
