A net force of 30 N is applied to a 10 kg object, which starts at rest. What is the magnitude of its momentum after 3.0 seconds?

Can someone please explain this as you go through the steps? I already know the equation is p=mv and I know that mass is 10kg and I just need v...

v1=0, v2 = ?
F•Δt = ,m•Δv = m• (v2-v1) = m•v2,
v2 = F•Δt/m =30•3/10 =9 m/s.
