A ball is dropped from a height of 10 m. If the energy of the ball reduces by 40% after striking the ground, how much high can the ball bounce back ? (g = 10m//s^2)

A particle is dropped from the top of a tower. It covers 40 m in last 2s. Find the height of the tower.

A pebble is dropped freely in a well from its top. It takes 20 s for the pebble to reach the water surface in the well. Taking g = "10 m s"^(-2) and speed of sound = 330 "m s"^(-1) . Find the time when sound is heard after the pebble is dropped.
