Answer
The SI unit of impulse is the same as the SI unit of momentum.
Work Step by Step
The units of impulse are: $N~s$
The units of momentum are: $\frac{kg~m}{s}$
We can verify that these are equivalent:
$N~s = (\frac{kg~m}{s^2})~(s) = \frac{kg~m}{s}$
The SI unit of impulse is the same as the SI unit of momentum.
