## Homework Statement

A stone is tied to a rope. The rope is spun vertically clockwise in circular motion. The rope has a constant speed. Draw four free-body diagrams of the stone when the angle between the rope and the positive x-axis is 0, 90, 180, and 270 degrees.

**2. The attempt at a solution**

0 degrees (stone is on the right): tension vector to the left, gravity vector pointing down, and centrifugal force pointing down.

90 degrees (stone is at the top): tension vector pointing down, gravity vector pointing down, and centrifugal force pointing right.

180 degrees (stone is on the left): tension vector pointing to the right, gravity vector pointing down, and centrifugal force pointing up.

270 degrees (stone is at the bottom): tension vector pointing up, gravity vector pointing down, and centrifugal force pointing to the left.
