A ball that has a mass of 1.00 kg is attached to a string 1.00 m long and is whirled in a vertical circle at a constant speed of 10.0 m/s.
a) Determine the tension in the string when the ball is at the top of the circle.
b) Determine the tension in the string when the ball is at the bottom of the circle.
c) Consider the ball at some point other than the top or bottom. What can you say about the tension in the string at this point?
