Circular path---) finding period 1. The problem statement, all variables and given/known data A 50-g weight tied to a string is twirled in uniform circular motion. If the circumference of the circular path is 207.3 cm and the weight completes 67.1 revolutions per minute, what is the period of the motion, in seconds? 2. Relevant equations V= 2* pi* r / T V= velocity r= radius T = period 3. The attempt at a solution ok so i converted the circumference to the radius first convert to meters = 2.07300 meters Then divide that by pi to get the diamater then by 2 to get the radius so i arrive at .330095 as the radius. Where i am stuck is how to convert the revolutions per minute to the velocity and im sure the weight comes into play . Any tips would be great thanks.
