**1. Homework Statement**

A ball on the end of a string is whirled around

in a horizontal circle of radius 0.28 m. The

plane of the circle is 1.44 m above the ground.

The string breaks and the ball lands 2.66 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/s

^{2}.

Find the centripetal acceleration of the ball

during its circular motion.

Answer in units of m/s

^{2}.

**2. Homework Equations**

T= [tex]\sqrt{}2y/g[/tex]

a

_{c}=4*pi

^{2}r/T

^{2}

**3. The Attempt at a Solution**

First I found time using this equation T= [tex]\sqrt{}2y/g[/tex]

=T= [tex]\sqrt{}2*1.44m/9.8m/s[/tex]= .5421047s

then I plugged my time into the acceleration equation a

_{c}=4*pi

^{2}r/T

^{2}

= 37.61415924 m. My answer is wrong and I would like to know what is it that I did wrong, I tried many ways to do it, but non of the answers I get are right, if you can please calrify. Thank you.
