Arowboat passenger uses an oar to push the boat off the dock by exerting a force of 60.0 n for 2.0s. what impulse acts on the boat?

Impulse is the change of momentum of an object when the object is acted upon by a force for an interval of time. It is simply calculated by the expression:

Impulse = F(change in time)
Impulse = 60(2)
Impulse = 120 Ns

Hope this answers the question. Have a nice day.
