Question
The superheroine Xanaxa, who has a mass of 63.5 kg, is pursuing the 74.3 kg archvillain Lexlax. She leaps from the
ground to the top of a 175 m high building then dives off it and comes to rest at the bottom of a 16.9 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 Ug change? Answer with a positive number. Assume g = 9.81 m/s?.
