Most 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 1.0×1013kghits the earth with an impact speed of 4.0×104m/s.

A) What is the earth's recoil speed after such a collision? (use reference frame in which the earth was initially at rest)

B) What percentage is the earth's speed around the sun?
