9702Gravitational potential energy and kinetic energy

A cannon-ball of mass 3.50 kg is fired at a speed of 22.0 m s⁻¹ from a gun on a ship at a height of 6.00 m above sea level. The total energy of the cannon-ball is the sum of the gravitational potential energy relative to the surface of the sea and the kinetic energy. What is the total energy of the cannon-ball as it leaves the gun?
