A uniform disk with a mass of 27.3 kg and a radius of 0.309 m is free to rotate about a frictionless axle. Forces of 90.0 N and 125 N are applied to the disk, as the drawing indicates.

(a) What is the net torque produced by the two forces?

(b) What is the angular acceleration of the disk?

• physics -

The drawing is needed to show where and in what directions the forces are applied to the disk.

Compute net torque.

angular acceleration =
(Net Torque)/(Moment of inertia)
