A few years ago, a movie came out about a soldier, John Carter, who was transported to Mars and could perform amazing feats of strength and jumping due to the lower Martian gravity. The surface gravity of Mars is 0.38 times that of earth. If John could lift 100 kg on earth (about right for a decently in shape and athletic person) how much mass in kg could he lift on Mars?
