Problem 2.22 (Multistep) A small space probe of mass 160 kg is launched from a spacecraft near Mars. It travels toward the surface of Mars, where it will eventually land. At a time 22.7 seconds after it is launched, the probe is at location <4400, 7200, 0m, and at this same instant its momentum is <46000, -7600, 0> kg m/s. At this instant, thanat o on due to the gravitational pull of Mars plus the air resistance acting on the...
