An elevator cable breaks when a 774 kg elevator is 22.9 m above a huge spring (k = 8.00104 N/m) at the bottom of the shaft.
(a) Calculate the work done by gravity on the elevatorbefore it hits the spring.
J
(b) Calculate the speed of the elevator just before striking thespring.
m/s
(c) Calculate the amount the spring compresses (note that work isdone by both the spring and gravity in this part).
