A meteor whose mass was about 10^8 kg struck the Earth (m = 6.0 X10^24 kg) with a speed of about 11 km/s and came to rest in the Earth.
(a) What was the Earth's recoil speed? (m/s)
(b) What fraction of the meteor's kinetic energy was transformed to kinetic energy of the Earth? (%)
(c) By how much did the Earth's kinetic energy change as a result of this collision? (J)
I know this problem requires a look at conservation of momentum and conservation of energy principles, but I am having trouble just trying to start this problem out :grumpy:
