5: A skier, m = 65 kg, glides on a perfect hill, 10 m high, no friction. However, at the bottom is a spring, k = 1500 N/m , system to stop the skier. A silly technique I will grant you. The spring is not perfect, it loses 800 J of energy every time the spring fully compresses or extends. Now we will have to assume the spring never extends past its equilibrium position. A: What is the speed of the skier when they hit the spring the first time down the ramp? B: How much does the spring compress the first time the skier hits it? C: The skier will be pushed back up the hill so the process will continue. How many cycles (n) will occur until the skier - eventually stops?
