A uniform disk with a mass of 35.5 kg and a radius of 0.424 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?

..and where is that drawing?
T=rxF
r- radius of rotation (point at which force F is applied)
T(total)= T1 + T2
T=IA
I- moment of inertia (I for the disk = (1/2)mR^2)
A- angular acceleration
A=T/I

Being a person that plays disc golf regularly I am going to say A I believe that the 90.0N and the 125N would be similar to the resistance from wind and atmosphere. But who knows I could be wrong.
