A car (mass = 1150 kg) is traveling at 32 m/s when it collides head-on with a sport utility vehicle (mass = 2550 kg) traveling in the opposite direction. In the collision, the two vehicles come to a halt. At what speed was the sport utility vehicle traveling?

• Physics -

momentum is conserved. If the end momentum is zero, the initial momentum was zero.

1150*32-2550v=0
solve for v.
