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?

Such an event may have been observed by medieval English monks who reported observing a red glow and subsequent haze about the Moon.
