A small space probe of mass 180 kg is launched from a spacecraft near Mars. It travels toward the surface of Mars, where it will eventually land. At a time 22.6 seconds after it is launched, the probe is at location <4000, 8700, 0> m, and at this same instant its momentum is <50000, -7400, 0> kg·m/s. At this instant, the net force on the probe due to the gravitational pull of Mars plus the air resistance acting on the...

4: Suppose the mass of a
rocket just as it runs out of fuel is 75550-kg, and its exhaust
speed is 2.7 × 103 m/s.
Calculate
the maximum rate, in kilograms per second, at which the rocket can
expel gases, if its acceleration cannot exceed seven times that of
the gravitational acceleration on the surface of the Earth. Assume
the gravitational force on the rocket is negligible.
