1. The problem statement, all variables and given/known data A ball is dropped from rest at a height of 50.0m above a spring. After the ball hits, it compresses the spring .340m. Ignoring any non-conservative forces, find the spring constant if the mass of the ball is 4.50 kg. 2. Relevant equations Hooke's law: k = mg/x 3. The attempt at a solution I'm not sure what to do. k = 4.50 kg x 9.8 m/s / 0.340 m = 129.71 That doesn't seem right. Help?
