Hammer and sickle on the Moon, dropped from different heights

  1. Jul 15, 2014 #1
    The hammer is at 200km and the sickle is at 100km above the Moon. As they fall down, the distance between them increases, or not? We need 'jolt' formula here, the rate of change of acceleration, right?

    Since the moon's gravity would be less at 200 km., the hammer would fall more slowly, so the distance would increase.
