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 2.0 km and a mass of 0.70 ×1013 kg hits the earth (6.0×1024 kg) with an impact speed of 3.9 ×104 m/s. What is the earth’s recoil speed after such a collision?
