The superheroine Xanaxa, who has a mass of 63.5 kg, is pursuing the 73.7 kg archvillain Lexlax. She leaps from the ground to the top of a 159 m high building then dives off it and comes to rest at the bottom of a 17.1 m deep excavation where she finds Lexlax and neutralizes him. Does all this bring about a net gain or a net loss of gravitational potential energy? loss O gain By how much will gravitational potential energy U, change? Answer with a positive number. Assume g = 9.81 m/s. U=
