How must of the roller coaster's kinetic and/or potential energy is in each of the points. for each point, pick one option. (sorry for the report, i found a mistake in my question and could not edit.) point a: a. 1/2 potential energy, 1/2 kinetic energy b. 1/2 potential energy, 0 kinetic c. 100 potential energy point b: a. 1/4 potential, 3/4 kinetic b. 100 kinetic, 0 potential b. 1/2 potential, 1/2 kinetic point c: a. 1/2 potential, 1/2 kinetic b. 3/4 potential, 1/4 kinetic c. 100 potential, 0 kinetic
