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
