$\begingroup$ Individually, the wedge increases in energy (kinetic) while the particle loses the same energy - its loss in potential energy is more than what it gains in kinetic. To solve the system you will also need conservation of momentum. $\endgroup$ - Macavity Aug 24 '15 at 10:0 Conservation of mechanical energy - problems and solutions. 1. An m-kg block is released from the top of the smooth inclined plane, as shown in the figure below. Comparison between the gravitational potential energy and kinetic energy of the block at point M is. Solution. Gravitational potential energy at point M : PEM = m g (1/3h) = 1/3 m. The conservation of energy formula goes Ki+Ui=Kf+Uf. U is potential energy and K is kinetic energy. In this case the golf ball at the start has zero potential energy. We are considering the surface of the moon to be the height h.
