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 1.0 × 103 kg hits the earth (6.0 × 1024 kg) with an impact speed of 3.8 × 10ª m/s. Part A What is the earth's recoil speed after such a collision? (Use a reference frame in which the earth was initially at rest.) Express your answer with the appropriate units. • View Available Hint(s) HÁ ? Value Units v =
