Well, if he doesn't slow down, then he'll hit the Earth at 86,000 mph. So, $$KE = \frac {mv^2}{2}$$ $$KE = \frac {158.3 kg\times (38445 m/s)^2}{2}$$ $$KE = 1.17\times 10^{11} N$$ I have no idea how to calculate the size of the carter it creates. Added: Now for a calculated guess: Assuming that half the energy is used to heat the ground and propel the ...
