the pendulum of a grandfather clock is 1.3m long. Determine the length of the arc through which the pendulum moves if it moves through an angle of 15

  • trig - ,

    circumference of the potential whole circle = 2π(1.3)
    = 2.6π

    so , by a simple ratio

    arc/2.6π = 15/360
    arc = 2.6π(15/360) = (13/120)π or appr .34 m
    or 34 cm
