A 0.50 kg ball that is tied to the end of a 1.5 m light cord is revolved in a horizontal plane, with the cord making a 30 degree angle with the vertical.

1. make a free body diagram for a conical pendulum

2. set the equations of motion for the ball

3. Determine the ball's speed.

4. if the ball is revolving with a 4.0m/s speed, what angle does the string makes with the VERTICAL

5. If the string can withstand max tension of 9.8 N what is the highest speed at which the ball can revolve?
