v^2/r

## The Attempt at a Solution

My physics midterm is tomorrow and I was doing review today, so I did this question, then looked at the professor's solutions. For the radius in both equations he used the length of the rope, but shouldn't the radius be Lsin20??? Also the way he positioned his y and x axis was that the Y axis was parallel to tension(EXTRA INFO).
