1. The problem statement, all variables and given/known data A horizontal spring with k = 71 N/m has one end attached to a wall and the other end free. An 95 g wad of putty is thrown horizontally at 3.7 m/s directly toward the free end. Find the maximum spring compression. 2. Relevant equations W=1/2kx^2 3. The attempt at a solution Tried squaring the 3.7m/s to get 13.69m^2/s^2 and multiplying that by the weight of the putty to obtain 1.3J, the work done. Plugging that in... W=1/2kx^2 1.3J=1/2(71)x^2 x=0.19 which is incorrect.
