M V not squared is equal to mg H not minus M G. This means that a half M V squared minus a half. So its initial kinetic energy or its final kinetic energy rather minus, its initial kinetic energy must equal the initial gravitational potential energy minus the final gravitational potential energy. So the change in kinetic energy for the dollar coaster must equal minus it's changing gravitational potential energy. So since there are no non conservative forces in the system to solve a V, we can apply the mechanical conservation of mechanical energy. At the top of the second peak, Which has a height age of 15 m. Now, the initial speed of the roller coaster we let BV not, which is two m per second and its initial hide H not which is 40 m. We want to know how fast it will be moving at the top of a subsequent hill, which has a height of 15 m. In this problem on the topic of energy conservation, we're told that a roller coaster at the top of the first hill is moving at a speed of 2m/s, and the height of the first hill is 40 m.
