Answer:
The answer is 2 kgm/s.
Step-by-step explanation:
We see that Impulse = FT = mv but in this case..
we have only a force and time which, of course happens to be the Impulse and NOT the momentum.
I = FT = P
(4)(0.5)
= 2 kgm/s or Ns?
Well the answer in fact is 2 kgm/s.
That is in fact the CORRECT answer not that it can not be identified. It can and is 2 kgm/s since we are talking about Momentum
