a. One of the main contributing factors to the extinction of the dinosaurs 65 million years ago was a large comet or asteroid that struck the earth. It threw up so much dust that the sun was blocked for a period of many months.
Suppose the asteroid had a mass of 40350000000000 kg and hit the earth (mass = 6 x 1024 kg) with an impact speed of 1850 m/s. What would be the earth's recoil speed after such a collision? (Use a reference frame in which
the earth was initially at rest.)
