A 0.410-kg block is attached to a horizontal spring that is at its equilibrium length, and whose force constant is 22.0 N/m . The block rests on a frictionless surface. A 6.00×10-2-kg wad of putty is thrown horizontally at the block, hitting it with a speed of 2.30 m/s and sticking.
How far does the putty-block system compress the spring?
