Vertical Circular Motion
A child is playing with a ball on a string. The ball has mass 0.065 kg, the string has radius 1.2 m.
Assume that the string is massless and neglect air resistance.
The child swings the ball on a string in a vertical circle. Halfway up the circle the speed of the ball is
measured to be 8.7 m/s. The child is doing no work on the system.
What is the maximum tension in the string?
Tmax = N
