###### Question: (13% Problem 1: The Moon's craters are remnants of meteorite collisions. Suppose a fairly large asteroid that has a mass of 5.25 x 102 kg (such an asteroid is about a kilometer across) strikes the Moon at a speed of 14 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? The mass of the Moon is 7.36 x 102 kg 9.986 10 9.986E-7 Correct 50% Part (b) What is the change in kinetic energy, in joules, 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 Grade Summary 4% 96 AKE Deductions Potential
