Last horizontal distance was 83 m hammer, what is the radial acceleration of the hammer just before liberation?

**2. Homework Equations**

Path equation - y=xtanTHETA - g / (2v0^2cos^2THETA) x x^2

**3. The Attempt at a Solution**

i set the details i know at the equation and i got a huge velocity 103.69 m/s

i put it in the equation a=v^2 / r but this is an astronom acceleration

what did i do wrong , i will glad for help and explanation...

thanks!
