A crate on a dock has a mass of 985kg. A crane lifts the crate a distance of 8.1metres up from the dock and moves it over the deck of a freighter. The crate then has 4.25x10 to the 4th joules of gravitational potential energy relative to the deck. How much higher is the deck of the freighter than the dock?
