A ball on the end of a string is whirled around in a horizontal circle of radius 0.467 m. The plane of the circle is 1.24 m above the ground. The string breaks and the ball lands 2.49 m away from the point on the ground directly beneath the ball’s location when the string breaks.

Question

A ball on the end of a string is whirled around in a horizontal circle of radius 0.467 m. The plane of the circle is 1.24 m above the ground. The string breaks and the ball lands 2.49 m away from the point on the ground directly beneath the ball’s location when the string breaks.
The acceleration of gravity is 9.8 m/s2 .
Find the centripetal acceleration of the ball during its circular motion.
Answer in units of m/s2
