1. The problem statement, all variables and given/known data A 4.63-kg ball of clay is thrown downward from a height of 2.69 m with a speed of 5.01 m/s onto a spring with k = 1610 N/m. The clay compresses the spring a certain maximum amount before momentarily stopping. b) Find the total work done on the clay during the spring's compression. 2. Relevant equations Us=integral(-kx dx) 3. The attempt at a solution From part of the question I found the maximum compression of the spring to be 0.50230 m, and I know that is correct. I thought that the total amount of work done on something by the spring's compression was equal to the integral that is in the relevant equations section. Therefore, that is what I did. I Us=integral(-kx dx) from 0 to 0.50230. The resulting answer was -203.106 J. But that is not correct, does anyone have some insight to what went wrong?
