1) A 0.53-kg chinchilla leaps from the roof of a Venetian palazzo, 50.0 m above the water line. A person in a lower story holds a net out of a window to catch the chinchilla, 4.00 m above the water line. a) How much work is done by gravity during the chinchilla's fall? b) What is the change in the gravitational potential energy of the chinchilla? c) If the gravitational energy is zero at the water line, what is the gravitational energy when the chinchilla is on the roof? d) What about when the chinchilla reaches the net? e) Answer (c) and (d) if the gravitational potential energy is taken to be 10.0 J at the water line.
