Calculating Tension in a Vertical Circle with a Demolition Ball Using Formulas

[Jrum6686]

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?
