A truck of mass ?1 starts at rest a distance ℎ1 above the bottom of a hill. It rolls down the hill and at the bottom the truck collides and locks bumpers with (sticks to) a car of mass ?2 which is at rest at the bottom of the hill in a completely inelastic collision. The two vehicles then roll together up a second hill. Assuming that both vehicles are in neutral and roll without energy loss due to friction or air resistance, how high above the bottom of the second hill will the two vehicles travel before stopping?

Helmholtz Free Energy

The Helmholtz free energy is a thermodynamic potential used to calculate the measure of useful work from a closed system. This system is kept at constant temperature and volume. German physicist Hermann Helmholtz introduced this concept in 1882.
