A car (mass = 1080 kg) is traveling at 25.4 m/s when it collides head-on with a sport utility vehicle (mass = 2750 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 - ,

    Since the 2 vehicles came to a halt,their momentums were equal.

    m1*Vi = m2*V2.
    1080*25.4 = 2750*V2.
    Solve for V2.
