Find what percentage of the gas propellant

Reference no: EM13659501

An astronaut in his space suit and with a propulsion unit (empty of its gas propellant) strapped to his back has a mass of 158 kilogram. During a space-walk, the unit, which has been totally filled with propellant gas, ejects some gas with a velocity of +32 m/s. As a result, the astronaut recoils with a velocity of -0.4 m/s. After the gas is ejected, the mass of the astronaut is 165 kilogram. Find what percentage of the gas propellant in the totally filled propulsion unit was depleted?
