4. Consider this 10 kg cart rolling up and down a hill. m= 10 kg V=5m/s h= 1m a. If the cart is initially rolling at 5 m/s at the beginning. how much kinetic energy does the cart initially have? b. If the hill has a maximum height of 1 meter will the cart make it over the top of the hill? (assume no friction). (hint, how much PE does a cart at 1m have?) c. When the cart is at the top of the hill does it have: (explain your answer) i. Only Potential Energy? ii. Only Kinetic Energy? iii. Both PE and KE?
