A uniform solid disk with a mass of 24.3-kg and a radius of .0.314 meters is free rotating about a frictionless axle. The axle is attached to a pedestal that holds the free-rotating disk off of the surface the pedestal is resting on. Looking at the disk/axle/pedestal assembly from the side perspective, an imaginary line can be drawn across the disks diameter, from the exact top of the disk, through the axle, and through the exact bottom of the disk. A force of 90.0 Newton's is being applied to the disk at a 90 degree angle to the imaginary line at the bottom of the disk pulling in the left direction. A force of 125 Newton's is being applied to the disk at a 90 degree angle to the imaginary line at the top of the disk pulling in the left direction. What is (a.) the net torque produced by the two forces and (b.) the angular acceleration of the disk?
