Question

Two 100kg bumper cars are moving towards eachother in oppisite directions. Car A is moving at 8 m/s and Car B at -10 m/s when they collide head on. If the resulting velocity of Car B after the collision is 8 m/s, what is the velocity of Car A after the collision

    Answer:

    -10 m/s

    Explanation:

    When two cars collide then the momentum of two cars will remains conserved

    • Mass of two cars = 100 kg
    • Speed of car A = 8 m/s
    • Speed of car B = – 10 m/s
    • After collision the speed of car B = +8 m/s

    By momentum conservation equation

                   m1v1i+m2v2i=m1v1f + m2v2f

                   (100)(8)+(100)(-10)=(100v)+(100)(8)\\                            v=-10 m/s
