The Moon's craters are remnants of meteorite collisions. Suppose a fairly large asteroid that has a mass of 4.95 x 1012 kg (such an asteroid is about a kilometer across) strikes the Moon at a speed of 13.5 km/s relative to the Moon. 50% Part (a) At what speed, in meters per second, does the Moon recoil after the perfectly inelastic collision?
