Simple Pendulum Question

  1. Feb 14, 2005 #1
    Simple pendulum has T = 2pi rt (l/g) when oscillating at a natural frequency of vibration. (Small angles of course)

    Calc. new T of pendulum when oscillating in a car with acceleration a.

    Any tips? Thanks. :)

    Can anyone do this question? Cheers.

    [tex]T=2\pi \sqrt{\frac{l}{\sqrt(a^2+g^2)}}[/tex]

    Thanks very much, it certainly was! I understand that totally! You found the effective g acting on the pendulum by summing the individual accelerations acting on the pendulum, using vectors. Great. :)
