A rifle fires two 4 g bullets at 2 kg target. The target is initially at rest and free to slide on a frozen pond while the gun is fixed to the ground. Each bullet leaves the rifle at 225 m/s and is imbedded in the target. Each collision conserves momentum. Each bullet strike is like a collision between carts that stick together. The rifle itself is irrelevant to the problem. Just consider the bullets and the target. Find the...
