An astronaut has a mass of 100 kg. She recedes from her spacecraft using spurts of gas from a small unit on her back. If the force generated by the gas spurt is 50 N, calculate her acceleration.

Answer 1

F = m a, so
a = F/m = 50 N/100 kg = 0.5 m/s^2
This will only be true when the "spurts" are coming out. For uniform acceleration you need a uniform rate of gas generation, not "spurts".
