Calculate the magnitude of the tension in the cable when the mass is at the bottom of the circle.?
A steel ball of mass 1.19 kg is attached to a thin (massless) cable and whirled around in a circle in a vertical plane. The circle has a radius of 1.14 m. When it is at the bottom of the circle, the ball has a speed of 11.1 m/s. Calculate the magnitude of the tension in the cable when the mass is at the bottom of the circle.

a = v^2 / r = 108.1 m/sec^2 Force due to the above acceleration = mass * 108.1 m/sec^2 Weight due to gravity = mass * 9.81 m/sec^2 Add the force and weight.
