## Homework Statement

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.

## Homework Equations

a = v^2/r

T = 2pi(r)/v

## 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?
