Q1: A 78-kg skydiver has a speed of 62 m/s at an altitude of 870 m above the ground. a. Determine the kinetic energy possessed by the skydiver. b. Determine the potential energy possessed by the skydiver. c. Determine the total work done by the skydiver. Q2: A 1000-kg roller coaster car moves from point A to B then C. (a) What is the potential energy at B and C relative to A? (b) What is the change in potential energy as it goes from B to C? (c) If the car starts from rest at point A, What is the speed of the car when it reaches point B? (Note: Figure is for Q2).
