A220-kg speedboat is negotiating a circular turn (radius = 31 m) around a buoy. during the turn, the engine causes a net tangential force of magnitude 590 n to be applied to the boat. the initial tangential speed of the boat going into the turn is 9.9 m/s. (a) find the tangential acceleration. (b) after the boat is 6.0 s into the turn, find the centripetal acceleration.
