Chapter 5, Problem 5.3.65(choose chapter or problem)
A roller-coaster car of mass 1.50 3 103 kg is initially at the top of a rise at point _. It then moves 35.0 m at an angle of 50.0 below the horizontal to a lower point _. (a) Find both the potential energy of the system when the car is at points _ and _ and the change in potential energy as the car moves from point _ to point _, assuming y 5 0 at point _. (b) Repeat part (a), this time choosing y 5 0 at point _, which is another 15.0 m down the same slope from point _.
