The Moon’s craters are remnants of meteorite collisions. Suppose a fairly large asteroid that has a mass of 4.95 × 1012 kg (such an asteroid is about a kilometer across) strikes the Moon at a speed of 14.5 km/s relative to the Moon. What is the change in kinetic energy, in joules, in the collision?
