1. The problem statement, all variables and given/known data A mass attached to a 43.9 cm long string starts from rest and is rotated 35 times in 57.0 s before reaching a final angular speed. Determine the angular acceleration of the mass, assuming that it is constant and determine the angular speed after 57 sec. 2. Relevant equations V=rW W=2pi*f f=1/T T=time it takes for one revolution 3. The attempt at a solution T=35/57 sec gives you T=.614 s I'm not sure where to go from there... am I missing an equation that links all of these together?
