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

**drwls**, Wednesday, April 28, 2010 at 2:08amAssuming that you have the correct velocity for the nail after it is hit (8.46 m/s), call that V and compute its kinetic energy with the usual formula,

KE = (1/2) M V^2

They only want the K.E. of the nail.
