1. The problem statement, all variables and given/known data A ball on the end of a string is whirled around in a horizontal circle of radius 0.366 m. The plane of the circle is 1.50 m above the ground. The string breaks and the ball lands 2.20 m (horizontally) away from the point on the ground directly beneath the ball's location when the string breaks. Find the radial acceleration of the ball during its circular motion. 2. Relevant equations a = v^2/r T = 2pi(r)/v 3. The attempt at a solution I know the radial acceleration is towards the center of the circle what i do not understand is that they do not give me time or velocity. so how i figure it out!? am i supposed to be assuming something?
