1. The problem statement, all variables and given/known data A 2 kg ball on a 3 meter long string swings along patch ABC. Angle AOB and AOC equal 30* each. Find the acceleration of the ball at point A. 2. Relevant equations Guesses: F=ma, v = vo + at 3. The attempt at a solution I tried using tan30 = X/2.6 and solving for X to find the horizontal distance. Then, draw a FBD and mg = 20 and the other leg is X, which would allow me to solve for the hypotenuse. But I realized that I cannot add a force with a distance.
