CHAPTER 11Most geologists believe that the dinosaurs became extinct 65 million years ago when a large comet or asteroid struck the earth,throwing up so much dust that the sun was blocked out for a period of many months. Suppose an asteroid with a diameter of 2.0km and a mass of 1.0 * 10¹3 kg hits the earth (6.0 * 1024 kg) with an impact speed of 4.0 * 10 m/s.a. What is the earth's recoil speed after such a collision? (Use a reference frame in which the earth was initially at rest.)b. What percentage is this of the earth's speed around the sun? The earth orbits the sun at a distance of 1.5 * 10¹¹ m.

We are given mass of asteroid. We are also given the velocity of the asteroid before collision. We…
