Question 17 ListenA blue lab cart is traveling west on a track when it collides with and sticks to a red lab cart traveling east. The magnitude of the momentum of the blue cart before the collision is 2.0 kilogram • meters per second, and the magnitude of the momentum of the red cart before the collision is 3.0 kilogram • meters per second. The magnitude of the total momentum of the two carts after the collision is1.0 kg • m/s2.0 kg • m/s3.0 kg • m/s5.0 kg • m/s

    option A

    Explanation:

    given,

    momentum of blue car in west direction = Pa = 2 kg. m/s

    momentum of red cart in east direction = Pb = 3 kg. m/s

    total momentum of the two cart = ?

    Pa = 2 Kg. m/s

    Pb = - 3 kg. m/s

    Total momentum

    P = Pa + Pb

    P = 2 - 3

    P = - 1 kg. m/s

    hence, the total momentum of the two carts after the collision is 1.0 kg•m/s

    The correct answer is option A
