Aball is dropped from a height of 150cm. the ball has a gravitational potential energy of 5j (jules) before it was released. as the ball falls to the flour, the gravitational potential energy and kinetic energy change.

determine the gravitational potential energy, kinetic energy, and total energy when the ball reaches a height of 90cm as it falls. assomr no energy if transferred to the air as thermal energy.
