A 5 kg object is released, from rest, at a height of h = 3 Rmoon above the surface of the Moon, where Rmoon = 1740 km is the radius of the Moon. The mass of the Moon is 7.3 x 1022kg. (a) What is its speed when it hits the surface of the Moon? The gravitational effects of the Earth/planets does not need to be Considered. (b) 7kg instead of 5 kg would change the energy by what percentage? (c) How much work did the Moon do on the object as it fell?
