1. (20 points. Use momentum and energy conservation to answer these questions. Show all work.) A green block with a mass of 3.1 kg is at the top of a 0.84 m high frictionless ramp. The block slides down the ramp onto a horizontal frictionless surface. The block then slides onto a rough surface with a coefficient of kinetic friction of 0.28 where it eventually comes to rest. A. Sketch the different phases of the motion (ramp, block on smooth surface, block on rough surface) and label with variables. B. Draw a free body diagram for the block sliding on the rough surface. Write Newton's 2nd law equations. C. List all known variables and their values. D. What is the energy type and amount at the top of the ramp? E. What is the kinetic energy and speed of the block after it slides down the ramp? F. How much thermal energy is produced as the block stops on the rough surface? Explain. G. How far does the block slide on the rough surface before it stops? H. How fast is the block moving when half of its energy has been converted the thermal energy due to
