Calculating centripetal acceleration

  1. Nov 2, 2008 #1
    A ball of mass m is suspended from a rope of length R. The ball is set into freely swinging circular motion in a vertical plane. The centripetal acceleration of the ball at the top of the circle is 13g. The centripetal acceleration of the ball at the bottom of the circle is closest to:

    A. 15g
    B. 17g
    C. 19g
    D. 16g
    E. 18g
