An astronaut in his space suit and with a propulsion unit (empty of its gas propellant) strapped to his back has a mass of 146 kg. The astronaut begins a space walk at rest, with a completely filled propulsion unit. During the space walk, the unit ejects some gas with a velocity of + 35 m/s. As a result, the astronaut recoils with a velocity of - 0.39 m/s. After the gas is ejected, the mass of the astronaut (now wearing a partially empty propulsion unit) is 165 kg. What percentage of the gas propellant was ejected from the completely filled propulsion unit?

    Answer: 9.5%

    Explanation:

    % deplected = Meject : (Meject+Mleft) * 100%

    Mleft = (165 - 146) kg = 19kg

    % depleted = 2.0 / (2.0 + 19) * 100=9.5%
