1. The problem statement, all variables and given/known data A bowling ball weighing 71.2 N is attached to the ceiling by a 3.80m rope. The ball is pulled to one side and released. It then swings back and forth like a pendulum. As the rope swings through its lowest point, its speed is 4.20 m/s. At that instant, find a) the magnitude and direction of the acceleration of the bowling ball and b) the tension of the rope. 2. The attempt at a solution I used ac= V2/r to find the acceleration, 4.6 m/s2. I know what magnitude and direction are, but I'm stumped on how to find them. Do I just use the rope as the y component? If so, how do I find an angle? I think I know how to do part b, but help there would be appreciated too! Thanks for your help!
