The Moon's craters are remnants of meteorite collisions. Suppose a fairly large asteroid that has a mass of 5.06 ✕ 1012 kg (about a kilometer across) strikes the Moon at a speed of 14.8 km/s. A. How much kinetic energy (in J) is lost in the collision? Such an event may have been observed by medieval English monks who reported observing a red glow and subsequent haze about the Moon. B. In October 2009, NASA crashed a rocket into the Moon, and analyzed the plume produced by the impact. (Significant amounts of water were detected.) Answer part (a) and (b) for this real-life experiment. The mass of the rocket was 2000 kg and its speed upon impact was 9000 km/h. speed of recoin (in m/s) loss of kinetic energy (in J)
