A 2490 kg demolition ball swings at the end of a 35.9 m cable on the arc of a vertical circle. At the lowest point of the swing, the ball is moving at a speed of 7.26 m/s. Determine the tension in the cable.

  • physics -

    Cable tension at bottom of swing =
    Weight + M*V^2/R

    R = 35.9 m
    M = 2490 kg
    V = 7.26 m/s
    Weight = M*g
