6) An Amazon package of mass m = 198 kg is released from re stat point A and slides on the friction less track shown. Point A is YA =

7.40 m above the ground. Point B is yg = 3.30 m above the ground. Ignore air resistance. a) Determine the potential energy of the Amazon package at Point A relative to the ground. (4 points) b) Determine the speed of the Amazon package at Point B. (4 points) c) The Amazon package hits the ground in a perfectly elastic collision. How high does the package bounce into the air (ignoring air resistance)? (4 points)
