Q1. Two spherical objects have a combined mass of 200. The gravitational attraction between them is 8.01×10-6 while their centers are 21.0 apart.

Q2. A 0.330 kg block is attached to the horizontal spring that is at its equilibrium length, and whose force constant is 19.20 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 the initial speed of 2.76 m/s and sticking. How far does the putty-block system compress spring?
