Well kinetic energy would be 0 unless you actually dropped the object. If the velocity is 0, then kinetic energy is 0. Potential energy = mgh. m = mass in kg. g = acceleration due to gravity, which is always 9.81 meters per second squared on Earth. h = height in meters. = (15kg)(9.81m/s/s)(508m) = 74752.2 joules. I think that's correct..
