Homework Help: Speed boat

  1. Apr 4, 2009 #1
    A speedboat with a length of 10.2m and a mass of 249 kg is negotiaging a circular turn (radius = 32 m) around a buoy. During the turn, the engine causes a net tangential force of magnitude 597 N to be applied to the boat. The intial speed of the boat going into the turn is 4 m/sec.
    a) What is the tangential acceleration of the boat, 2 sec into the turn?

    b) What is the tangential velocity of the boat, 2 sec into the turn?

    c) What is the centripetal acceleration, 2 sec into the turn?

    d) What is the total acceleration, 2 sec into the turn?

    for a, Tan Accel= pi*angular acceleration. but i dont know really how to get started.
