Potential energy = U = m g h
so drop in U = mg (8.25 - 4.32) = 3.93 m g Joules
that becomes kinetic energy, Ke = (1/2) m v^2
Ke = 3.93 * 0.358 * 9.81 if on earth
= 13.8 Joules
An object with a mass of 358 g is released from a height of 8.25 m. Find its kinetic energy 4.32 m above the ground. There is no air resistance.
