A 5 kg object is released, from rest, at a height of h = 3 R moon above the surface of theMoon, where R moon = 1740 km is the radius of the Moon. The mass of the Moon is 7.3 x10 22 kg.(a) What is its speed when it hits the surface of the Moon?The gravitational effects of the Earth/planets does not need to beConsidered.(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?
