You create a centripetal force apparatus consisting of a mass m attached to the end of a string and spun in a uniform circular path of radius R, where R = 65.5 cm. The mass is spun in a uniform circular path for 60.0 seconds, during which a total of 117 revolutions are completed.

Question

You create a centripetal force apparatus consisting of a mass m attached to the end of a string and spun in a uniform circular path of radius R, where R = 65.5 cm.  The mass is spun in a uniform circular path for 60.0 seconds, during which a total of 117 revolutions are completed.

(a) What is the period, T, of the motion of the mass around its uniform circular path?  (In other words, how many seconds does the mass require to go around the uniform circular path once?)
60/117 = 0.513 
Is this correct? I feel like it should be more difficult.
