  1. Hmmmmm. Impulse is equal to change in momentum. There is no change mentioned here

  2. I think the answer is this:

    The change of momentum of a system is equal to the net impulse applied to it. Therefore,

    delta p=Fnet*deltat=Impulse

    In our case, p initial=mv=28kg*13m/s=364 kg*m/s
    p final=0 ( the object stops, v=o, p final 0)

    delta p = p final- p initial = 0- 364 = -364 kg*m/s

    Hope, that's the right answer.
