. A crane lifts a car, with a mass of 1.5x10*kg, at a constant velocity, to a height of 14m from the ground. It turns and drops the car, which then falls freely back to the ground. Neglecting air friction, find " The work done by the crane in lifting the car " The gravitational energy of the car at its highest point, in relation to the ground " The velocity of the car just before it strikes the ground after falling freely from 14m
