You decide to make a simple pendulum by attaching a bowling ball to a very light wire and suspending it from the ceiling in your garage. The length of the wire is 1.75 m and the mass of the bowling ball is 5 kg. If you pull the bowling ball back an angle of 15 degrees from the vertical and release it, how fast will the bowling ball be moving when it passes through equilibrium?

  • Physics -

    PE of ball when released is mgh
    KE of ball at bottom of swing is the same, and is 1/2 mv^2.

    get PE, solve for v
