Homework Help: Science: Physics

Posted by Joan on Thursday, January 6, 2011 at 12:09am.

A physics teacher shoots a .30 caliber rifle at a 0.47 kg block of wood. The rifle and wood are mounted on separate carts that sit atop an air track (like a linear air hockey table--ie. frictionless). The 5.7 kg rifle fires a 27 gram bullet at 227 m/s in the positive direction.
What would be the velocity of the rifle after the bullet is fired?
And, what would be the velocity of the block of wood with the bullet lodged inside?
