We will later discuss how we can arrive at this result but it is worth noticing that, due to this relationship, we can tell that the units for impulse in the SI system are $ \mathrm{\frac{N}{s}} $, this is, units of force times units of time. Since the algebraic sum of the area under the graph is $0$, the impulse is $0$. Momentum equals mass times velocity, so to find speed (the magnitude of velocity), you solve for v: 0.44 m/s.
