Question

A simple pendulum, 1.00 m in length, is released from rest when the support string is at an angle of 35.0 from the vertical. What is the speed of the suspended mass at the bottom of the swing? (g = 9.80 m/s2 and ignore air resistance)

    Answer:

    Explanation:

    Length = 1.00 m

    If the length is 1.0, the vertical distance pivot to bob is cos 35 = 0.819

    At the lowest point, vertical distance is 1.0, so the change is the difference, 0.181 meter

    The potential energy of that height is converted to kinetic energy of motion, which determines the speed.

    PE = KE

    mgh = ½mV²

    V = √(2gh) = 1.88 m/s
