Unformatted text preview: There is no net torque on the system here so the total I ϖ of the system is the same before and after. a) Find the final angular velocity of the system if the initial angular velocity of the ring is zero and the initial angular velocity of the disk is ϖ i = 20rad/s. Show your reasoning. ϖ i = 0 ϖ i = 20rad/s ϖ f = ? rotate together I ring = mr 2 = 0.16kg m 2 I disk = 1 / 2 mr 2 = 0.24kg m 2...
