Question

An elevator cable breaks when a 925 kg elevator is 24.0 m above the top of a huge spring (k = 9.50×10^4 N/m) at the bottom of the shaft. Part A Calculate the work done by gravity on the elevator before it hits the spring. Part B Calculate the speed of the elevator just before striking the spring. Part C Calculate the amount the spring compresses (note that here work is done by both the spring and gravity).

          An elevator cable breaks when a 925 kg elevator is 24.0 m above the top of a huge spring (k = 9.50×10^4 N/m) at the bottom of the shaft.

Part A
Calculate the work done by gravity on the elevator before it hits the spring.

Part B
Calculate the speed of the elevator just before striking the spring.

Part C
Calculate the amount the spring compresses (note that here work is done by both the spring and gravity).

Step 1

Given: Mass of elevator, m = 925 kg Height, h = 24.0 m Acceleration due to gravity, g = 9.8 m/s^2 Work done by gravity = mgh Work done by gravity = 925 kg * 9.8 m/s^2 * 24.0 m Work done by gravity = 217560 J Therefore, the work done by gravity on the elevator Show more…
