A 1209 kg safe is 1.54 m above a heavy-duty spring when the rope holding the safe breaks. Thr safe hits the spring and compress it 53 cm. What is he spring constant of the spring?
The Attempt at a Solution
I thought I understood momentuem and energy but not anymore. Here is what I did....
Then solved for V and got 5.494 m/s
Then used that velocity for the spring constant by using......
then solved for k and got 129912 N/m...... but that is coming up wrong what am i doing wrong.
