Homework Statement


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?

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.
