A rifle fires two 4-g bullets, one at a time, at 500-g 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. Find the final velocity of the target after each bullet strike. You must keep three decimal places in your calculations in order to get the correct answer. • You should have two momentum diagram pairs, one for each collision process. • You should have two answers to this problem. You figure out the units! [1.786, 3.543] • The rifle itself is irrelevant to the problem. Just consider the bullets and the target. • What do you have to assume about friction between the target and the pond ice? What about air resistance? • Tip for Evaluation: Consider the magnitude of the target velocity compared to the bullet's initial velocity. Why is it reasonable that the targettbuullet's final velocity vWould be so much smaller that the bullet's initial velocity? (almost 100y smaller in fact!)
