1. The problem statement, all variables and given/known data A force of 2.2N acts tangentially to the rim of a solid 52kg disk, with a radius of 32cm. How long does it take to accelerate the disk, rotating about an axis though it's center and perpendicular to it's plane, from rest to 210 rev/min? 2. Relevant equations Idisk=.5mr^2 T=I (wierd fish symbol) fish symbol = Wf - Wi t 3. The attempt at a solution i dont know how to find the wierd fish symbol.. one because i dont know what it stands for and two. i need that inorder to find time.. HELP PLEASE!?
