Homework Statement
An elevator cable breaks when a 798 kg elevator is 28.9 m above a huge spring (k = 8.00 multiplied by 104 N/m) at the bottom of the shaft.
(a) Calculate the work done by gravity on the elevator before it hits the spring. I got 226009 which is right
(b) Calculate the speed of the elevator just before striking the spring. I got 23.8 which is right
(c) Calculate the amount the spring compresses (note that work is done by both the spring and gravity in this part).
I need help with C!
