Thank you both so much!

I would use xf = xi + vi*t + .5at^2 to find the distance after a given time...or I could use vf^2 = vi^2 + 2ad... I do not know how this relates...do I need to find tangential acceleration of the disk?? If so, how do I find the radius??

I found Wf after the first 5 seconds to be 29.4 rad/s...I found this by dividing the total radians traveled by the time it took. I used this value as the Wf in the speeding up equation, and the Wi in the slowing down equation. Is that incorrect? and thanks for the welcome!

I converted the amount of rotations completed in 5 seconds into radians. 23.4 rot * 2pi = 147 rad I found the angular acceleration of the object in the first 5 seconds it was speeding up. Wf = Wi + at a = 5.881 rad/s^2 I then used the moment of inertia given in the problem to solve for torque. T...
