Homework Help: Simple Harmonic Motion and Elasticity

  1. Jul 31, 2009 #1
    1. The problem statement, all variables and given/known data
    A 0.01 kg bullet is fired horizontally into a 2.50 kg wooden block attached to one end of a massless, horizontal spring (spring constant = 845 N/m). The other end of the spring is fixed in place, and the spring is unstrained initially. The block rests on a horizontal, frictionless surface. The bullet strikes the block perpendicularly and quickly comes to a halt within it. As a result of this completely inelastic collision, the spring is compressed along its axis and causes the block/bullet to oscillate with an amplitude of 0.200 m.
    What is the speed of the bullet?

    2. Relevant equations
    I only wish I knew...

    3. The attempt at a solution
    I'd love to try this problem, since it is for extra credit, if anyone has any suggestions...

    Wow, sorry if you read all that, but I didn't realize the teacher changed the EC question. We aren't doing that one anymore luckily.
