1. The problem statement, all variables and given/known data A 1.08 kg block is attached to a horizontal spring with spring constant 3650 N/m. The block is at rest on a frictionless surface. A 10.6 g bullet is fired into the block, in the face opposite the spring, and sticks. What was the bullet's speed if the subsequent oscillations have an amplitude of 7.10 cm? 2. Relevant equations This is the only formula I can think of but I do not have time? Vx=-VtsinO=-Awsinwt 3. The attempt at a solution I do not know which formula I could use to start the problem... HELP!
