1. The problem statement, all variables and given/known data An elevator cable breaks when a 760 kg elevator is 29 m above the top of a huge spring (k = 8.00 × 104 N/m) at the bottom of the shaft. (a) Calculate the work done by gravity on the elevator before it hits the spring. (b) Calculate the speed of the elevator just before striking the spring. (c) Calculate the amount the spring compresses (note that here work is done by both the spring and gravity). 2. Relevant equations 3. The attempt at a solution I got 215992 J for a, 23.8 m/s for b, and I need help with c. Thanks!
