A steel safe with mass 2200 kg falls onto concrete. Just before hitting the concrete its speed is 40 m/s, and it smashes
without rebounding and ends up being 0.06 m shorter than
before. What is the approximate magnitude of the force exerted
on the safe by the concrete? How does this compare with the
gravitational force of the Earth on the safe? Explain your analysis
carefully, and justify your estimates on physical grounds.
