Chapter 8, Problem 8.61(choose chapter or problem)
A 70-kg astronaut floating in space in a 110-kg MMU (manned maneuvering unit) experiences an acceleration of \(0.029\mathrm{\ m}/\mathrm{s}^2\) when he fires one of the MMU’s thrusters.
(a) If the speed of the escaping \(\mathrm{N}_{2}\) gas relative to the astronaut is 490 m/s, how much gas is used by the thruster in 5.0 s?
