The diagram shows a roller-coaster track. Assume that the system is closed.
At point E, the roller-coaster car has just exited the vertical loop.
Which statement best describes the relative amounts of potential and kinetic
energy of a roller-coaster car at point E?
O A. Kinetic energy is at almost 0%, and potential energy is at almost
100%
O B. Both kinetic and potential energy are at almost 0%.
O C. Both kinetic and potential energy are at almost 100%.
OD. Potential energy is at almost 0%, and kinetic energy is at almost
100%
