The spring shown in the figure to the right is compressed d = 50 cm and used to launch a person sitting on a sled with total mass m = 100 kg. After a decline with height h1 = 10 m, there is an incline with angle = 30o. a. Explain if energy and/or momentum are conserved as the person on the sled moves down and up the hills. Use this to argue which method is most appropriate to solve the problem. b. What is the velocity of the person just as they lose contact with the spring? c. What is the velocity of the person at the bottom of the decline? d. How far does the person travel on the incline before they stop? Measure this distance along the incline, not in the horizontal or vertical directions
