Find the tangential acceleration

Reference no: EM13545705

A 240-kg speedboat is negotiating a circular turn (radius = 36 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 7.1 m/s. (a) Find the tangential acceleration. (b) After the boat is 4.0 s into the turn, find the centripetal acceleration.
