1. The problem statement, all variables and given/known data A small gear with mass m and radius r rotate around a central axis. A force is applied to an interior hub at a radial distance r/2 from the axis. A. If a force of 4N is applied for 10s, what is the angular velocity of the small gear, assuming it starts at rest? B. Once it reaches this speed, the small gear is engaged with a larger gear next to it, of mass 4m and radius 4r. If the angular speed of the small gear is maintained, what is the angular velocity of the larger gear, assuming no slipping? 2. Relevant equations F=MAt R x alpha= At omega= omega initial + alpha x T I=1/2 MR^2 3. The attempt at a solution For the first piece, I tried to answer it by setting up F=MAt as 4=MAt and At=r x alpha, and then setting them equal and solving for omega, and then plugging them in to omega= omega initial + alpha x T. I feel like this isn't correct and that it is leaving out some key pieces. Any help is appreciated.
