Homework Help: Physics

Posted by Kelly on Tuesday, April 27, 2010 at 10:52pm.

The collision between a hammer and a nail can be considered to be approximately elastic. Estimate the kinetic energy acquired by a 13 g nail when it is struck by a 550 g hammer moving with an initial speed of 4.0 m/s.

I solved for the final velocities of both and got 3.8 m/s for the nail and 8.46 m/s for the nail.

How do I get my final answer.. I'm so close! haha
