(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

confession Olympic hammer competition, competitor turns mass 7.3 kg ball at the end of a metal cable length 1.2 meters. Throw the hammer was released some 1.3 meters high 21 ° angle above horizon.

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

2. Relevant 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!
