Q1. A 0.507 kg block is attached to a horizontal spring that is at its equilibrium length, and whose force constant is 15.1 N/m. The block rests on a frictionless surface. A 0.0520 kg wad of putty is thrown horizontally at the block, hitting it with a first speed of 2.43 m/s and sticking. How far does the putty-block system compress the spring?

Q2. A 378 N, uniform, 1.56 m bar is suspended horizontally by two vertical cables at each end. Cable A can support a maximum tension of 502.0 N without breaking, and cable B can support up to 397.0N. You want to place a small weight on this bar. What is the heaviest weight you can put on without breaking either cable?
