1. The problem statement, all variables and given/known data A 10.0-g bullet is fired into and embeds in a 2.00-kg block attached to a spring with a spring constant of 19.6 N/m and whose mass is negligible. How far is the spring compressed if the bullet has a speed of 300 m/s just before it strikes the block, and the block slides on a friction-less surface? 2. Relevant equations F=kx 3. The attempt at a solution I tried to solve for the momentum of the system after the impact, which is mass * velocity = 0.01 kg * 300 m/s = 3 N*s. Don't know where to go from there...help.
