A 0.655kg stone is moving in a vertical circular path attached to a string that is 68.0cm long. The stone is moving around the path at a constant frequency of 2.35 rev/sec.
1. Find the tension in the string at the lowest point, and the highest point.
2. Draw a complete free-body diagram for one complete revolution of the stone. Select the angle delta=0 at the lowest point of the path
3) At the moment the stone is overhead, the stone is released. What is the direction and magnitude of the velocity of the stone when it leaves the circular path?
