Thank you for all of the correct answers. Everyone got it right.
It has always perplexed me how there are two conserved quantities, energy and momentum, both related to intimately to force.

Change in momentum!

Force is rate of change in momentum
= change in momentum / time
Force* time = change in momentum

The easiest way to keep this straight is through dimensional analysis. Here is a list of a few items with their dimensions:
Force................. m x t^-2
Energy................m x^2 t^-2
Momentum..........m x t^-1
F x Distance....... m x^2 t^-2 = Enegy
F x Time..............m x t^-1 = Momentum

Yeah change in momentum.
You could use this concept of
E = F*d and M = F*t to work out this problem I posted a while back.

Change in momentum. We can see this if we know that F = ma; so that F = mv/t and Ft = mv = p. Then delF t = m delv = delp, which is the change in momentum.
And same to you, too.

its simple.... if you know Newtons Second Law of Motion....
The change in linear momentum is the product of force and time....
