Homework Help: Radial and Tangential Acceleration Question!

  1. Sep 1, 2010 #1
    A ball tied to the end of a string 0.5 m in length swings in a vertical circle under the influence of gravity. When the string makes an angle of 20 degrees with the vertical, the ball has a speed of 1.5 m/s. Find the tangential component of acceleration at this instant. Help!

    Tangential Acceleration = dv/dt

    I could figure this out but I can't figure out the velocity function. HELP me please!

    What forces act on the ball? What tangential force acts on the ball?
