1. The problem statement, all variables and given/known data A 0.40 kg mass, attached to the end of a .75 m string, is whirled around in a circular horizontal path. If the maximum tension that the string can withstand is 450 N, then what maximum speed can the mass have if the string is not to break? 2. Relevant equations F=m*a T=r*F*sin(theta) v=r*omega 3. The attempt at a solution I have absolutely no idea where to even begin with this. My idea was to find the acceleration when the force is 450 N, but that yields the linear acceleration not the angular one which does nothing for me. I am stumped.
