Question

Having successfully boarded the cargo vessel, Defiance Drake removes her emergency spacesuit, complete with its 10.0 kg atmospheric bottle. Surprisingly, she encounters no human crewmembers, but finds that the ship is host to at least one Enyaki warrior (mission: destroy all humans). She and the alien float weightless in the freighter, at rest with respect to each other. Defiance decides to whip her air canister at the alien and flee. She exerts a constant force of 240. N on the canister for 0.50s. The impact propels the Enyaki warrior (mass of 100. kg) backwards into the padded wall of the ship, which is compressed by 0.04 m as the alien comes to a stop.
