An 800.0 kg car containing an 80.0 kg crash dummy is moving at 15 m/s. The car is smashed into a concrete walls and stops in 6.00x10^-2 seconds.

What is the change in momentum of the car?

  • Physics -

    The car lost all its momentum if it stopped

    The dummy may have stopped and may have kept going through the windshield for all we know so it is not part of the problem (unless there s a part B which you have not gotten to yet.)
    Or perhaps that is part C because surely the problem also wants to know the average force on the car which is (change in momentum / time)
