Homework Help: Tension prob

  1. Oct 27, 2007 #1
    A 1210 kg demolition ball swings at the end of a 28.0 m cable on the arc of a vertical circle. At the lowest point of the swing, the ball is moving at a speed of 6.38 m/s. Determine the tension in the cable.

    What formula/s would I use to figure this out?

    What is the shape of the arc the ball swings through?

    What makes the ball follow that arc?
