    2.25 Newton. seconds

    Explanation:

    Impulse is a rate of change of the momentum. It is calculated as a product of the average force over a time interval. Both measures are given here, so we can just apply the formula:

    (impulse) = (avg. force) x (duration) = (750 N) x (0.003 s) = 2.25 N. s
