Two 2 kg carts are initially at rest at the top of a pair of ramps as shown: The initial height of cart 1 is h = 11] cm. The initial height of cart 2 is 39;; = 6 cm. The two carts are released at the same time. 3} Using energy conservation, determine how fast each cart is moving when they reach the bottom of each of their ramps. h] The carts go on to collide and stick together. Use momentum conservation to determine hornr fast they are moving after they stick. :1 After a while, the pair of carts will go up one of the ramps while they roll together. How high up do they get? d] Compare the total potential energy at the beginning of the scenario to the potential energy of the system from part (cl. What accounts for the loss of energy
