A ball on the end of a string is whirled around in a horizontal circle of radius 0.300 m. The plane of the circle is 1.40 m above the ground. The string breaks and the ball lands 2.30 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.
