A) Since density is “rho=frac{m}{V}” , then “m=rhotimes V=0.8times160times10^{-6}times150” “=1.92times 10^{-2}” kg.
B) According to the law of conservation of momentum, the gas pulse is transmitted to the astronaut’s pulse “m_gtimes v=Delta p_a” , since “F=frac{Delta p_a}{Delta t}=atimes M”, then “a=frac{m_gtimes v}{Delta t times M}= frac{1.92times 10^{-2}times 150}{1 times 130}approx0.02” m/s“^2” .
