ws Practice Identifying Conservation of Energy and Conservation of Momentum Instructions: In each scenario, identify where conservation of energy can be applied and where conservation of momentum can be applied. When applying conservation of energy, identify what is "before" and what is "after". Also, indicate what types of energy are in the system for each case. When applying conservation of momentum, identify what is "before" and what is "after" and write out the conservation of momentum equation. Example 3 A block is attached to a light horizontal spring and is at rest on 15.0 kg 3.00 kg 800 m/s a smooth horizontal surface. Suddenly, it is struck by a stone O- traveling horizontally to the right. After the collision, the stone rebounds horizontally to the left. Example 4 A frame is suspended from a coil spring. A lump of putty is dropped from rest onto the frame from a height of 30.0 cm. After the putty lands on the frame, the frame moves downward from its initial position. 30 0 cm
