A block of mass m is pushed against (but not attached to) a spring with stiffness k so that the spring is compressed a distance Ar. When released, the block slides across the frictionless surface of a shelf a height h above the floor, the then falls to the floor. a. What is the speed of the block at the moment it leaves the shelf? V2 = b. What is the speed of the block at the moment just before it hits the ground?
