F = ma
Since we are given velocity (speed with a direction component) and time, it would be:
F = m(v/t)

Deceleration Force

You need to know the change in speed. If you have the initial speed and the final speed, the change is the difference between them. If you assume that deceleration is uniform, you simply divide the change in velocity (or speed) by the change in time (or the elapsed time), you get the acceleration, which we sometimes call deceleration when the speed decreases. You multiply acceleration by mass to get the force, because F = ma.

We know that F = ma (Force = mass x deceleration)
And that a = ∆v/t (deceleration = change in velocitytime)
Hence F = m∆v/t (Force = mass x change in velocity/time)

F=ma
a=dv/dt (negative for decelerating body)
dF=m dv/dt
And yea, don't forget the vector signs.

Terminolgy Pointer. Decceleration is an ugly word. Acceleration is the term you want. "ANY" change in velocity is acceleration, negative or positive.

F = -m|(delta)v|/t
