    Answer:

    A) 28000kgm/s

    B) 6.40kgm/s

    Explanation:

    Momentum = mass * velocity of a body

    A) Given

    mass m = 2500kg

    velocity v = 11m/s

    Substitute

    Momentum = 2500 * 11

    Momentum  = 27500kgm/s

    Momentum = 28000kgm/s (to 2 sf)

    B) Given

    mass m = 200g = 0.2kg

    velocity v = 32m/s

    Substitute

    Momentum = 0.2 * 32

    Momentum  = 6.4kgm/s

    Momentum = 6.40kgm/s (to 2 sf)
