F) a 55 kilogram diver falls freely from a diving platform that is 3.00 meters above the surface of the water in a pool. when she is 1.00 meter above the water, what are her gravitational potential energy and kinetic energy with respect to the water's surface?

Estimate the kinetic energy of the neptune with respect to the sun as the sum of the terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. [assume the neptune is a uniform sphere with mass = 1.0×1026 kg , radius = 2.5×1010 m , rotation period 16.1 h , orbital period 6.01×104 d and is 4.6×109 km from the sun.]
