Chapter 1, Problem 73GP(choose chapter or problem)
A meteor whose mass was about \(1.0 \times 10^8 \mathrm{~kg}\) struck the Earth \(\left(m_{\mathrm{E}}=6.0 \times 10^{24} \mathrm{~kg}\right)\) with a speed of about \(15 \mathrm{~km} / \mathrm{s}\) and came to rest in the Earth.
(a) What was the Earth's recoil speed?
(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?
