Question

Part A What was the Earth's recoil speed? Part B What fraction of the meteor's kinetic energy was transformed to kinetic energy of the Earth? Part C By how much did the Earth's kinetic energy change as a result of this collision? Part B What fraction of the meteor's kinetic energy was transformed to kinetic energy of the Earth? Part C By how much did the Earth's kinetic energy change as a result of this collision? Part C By how much did the Earth's kinetic energy change as a result of this collision? A meteor whose mass was about 1.910^8 kg struck the Earth (mE = = 6.0 x 10^ 24 kg) with a speed of about 16 km/s and came to rest in the Earth. Part A What was the Earth's recoil speed? Part B What fraction of the meteor's kinetic energy was transformed to kinetic energy of the Earth? Part C By how much did the Earth's kinetic energy change as a result of this collision?
