Most geologist 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 2.0 km and a mass of 1.0×10^13kg hits the earth with an impact speed of 4.0×10^4m/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? (use the astronomical data inside the back cover.)
