A 234 kg boat is negotiating a circular turn (radius = 33.1 m) around a buoy.  During the turn, the engine causes a net tangential force of magnitude 995 N to be applied to the boat.  The initial tangential speed of the boat going into the turn is 20.6 m/s.  Find the angular velocity after 2.5 seconds. Use g=9.8
