did the force act on the mass?

forces cause changes in the momentum of an object

newton's second law tells us:

F=ma =Δ(mv)/Δt

so Δt=Δ(mv)/F
=3kgm/s/6N = 0.5 s

Change in momentum = Force x Time
3 = 6 x Time

Time = ½ s

(Fnet)(change in time)= (Pf-Pi)

(6)(delta t)= 3

delta t = 0.5 seconds

This is really a no-brainer.

Force × time = change in momentum

They give you "force."
They give you "change in momentum."
Solve for "time."
