Calculate the potential energy, kinetic energy, and velocity at points A - E, as shown. Neglect Friction 1200 10 m/s 30 m 20 m 16 m 10 m Hint: By the conservation of energy, the total energy of the roller coaster at all points is equal. Therefore, if the total energy at point A can be calculated, then it will be equal to the total energy at points B - E.
