The period T (time in seconds for one completecycle) of a simple pendulum is related to the length L(in feet) of the pendulum by the formula8T^2=pi^2L. If achild is on a swing with a 10-foot chain, then how longdoes it take to complete one cycle of the swing?

  • math -

    solve for T

    T= PI sqrt (L/8)
