Impulse is equal to change in momentum of an object. The only way to change an object's momentum is to apply a force for certain amount of time.

Impulse is calculated as follows: Δp = F * t

Put your values in the right spots and solve for F. In this case since F is multiplied by Time, you will divide both sides by the time to find your answer.
