## Problem

Two bumper cars are driven toward each other. The initial momentum of bumper car 1 is 250, point, 0, start text, k, g, end text, dot, start fraction, start text, m, end text, divided by, start text, s, end text, end fraction and the initial momentum of bumper car 2 is minus, 320, point, 0, start text, k, g, end text, dot, start fraction, start text, m, end text, divided by, start text, s, end text, end fraction. After the cars collide, the final momentum of bumper car 1 is minus, 311, start text, k, g, end text, dot, start fraction, start text, m, end text, divided by, start text, s, end text, end fraction.
What is the magnitude of the final momentum of bumper car 2?
