the momentum of 900kg car initially moving north at 10m/s increases by 10,800. calculate the final velocity of the car.

  • physics -

    The diomensions of your momentum change must be included.
    Is it 10,800 kg*m/s?
    If so, the velocity increases by 10,800/900 = 12 m/s, making the new velcoity 22 m/s
