A block is placed on a frictionless ramp at a height of 13.5 m above the ground. Starting from rest, the block slides down the ramp. At the bottom of the ramp, the block slides onto a frictionless horizontal track without slowing down. At the end of the horizontal track, the block slides smoothly onto a second frictionless ramp. How far along the second ramp does the block travel before coming to a momentary stop, as measured along the incline of the ramp?

A block of mass M sits at rest at the top of a frictionless curved ramp of height h. After being released, the block is moving with speed 4v when it collides with a block of mass 1.5M at the bottom of the ramp. Immediately following the collision, the larger block has a speed 2v. The second block is attached to a vertical rope, and swings freely as a pendulum after the collision. The pendulum string has length L. a)...
