Some of the energy is lost (dissipated) in the process of rebounding. Also, air resistance can slow down the ball a bit.
It is because the ball is inelastic. Some energy is lost when it bounces off the ground.

They will both hit the ground at the same time.
Weight and height. The potential energy of an object is its weight times its height. The potential energy is turned into kinetic energy as the object is dropped. Potential energy is weight times height, kinetic energy is one half mass times velocity-squared. Mgh = ½ M V^2 To reach a speed of 10 m/s this equation can be solved to show that the object must be dropped through a height of 5.1 metres.
Momentum and kinetic energy, but this is true only up to a point. Objects dropped in Earth's atmosphere will reach a "terminal velocity" when the force of gravity equals the force of friction or air resistance. The height at which this happens will depend on its mass, density, and shape.

drop a heavy object and a light object from the same height at the same time. time it with a stopwatch, or just watch them.

The maximum height the roller coaster can/will reach
it varies. they mostly stop growing once they go through puberty.On average, girls reach full height at 16 and boys reach their full height at 18-20.

The ADA states: Side-reach Telephone: The Maximum height is 54". If side-reach Occurs over an obstruction 24" wide and 34" high, the maximum height allowed is 46" Forward-reach Telephone: The maximum Height allowed is 48". If forward-reach Occurs over an obstruction 20"to 25", the maximum height allowed is 44"
