Homework Help: Physics

Posted by Fred on Thursday, October 14, 2010 at 12:34am.

A bullet with a mass of 55 grams moving with a speed of 100 m/s slams into and wedges in a 1.9 kilogram block of wood supported by a string initially at rest. Which one, conservation of energy or conservation of momentum, can be applied to this situation? Why?

I think it's conservation of momentum because kinetic energy is not conserved in inelastic collisions. Correct?
