A 5-gram bullet going 200m/s hits a 40-gram "tin can" resting on a fence post. The bullet passes through the can emerging with a speed of 160m/s in the same direction. How fast, in the same direction, does the can go after the bullet has passed through.

Momentum applies.

5*200+ 40*0=5*160+ 40V
solve for V
