A solid puck with radius R1 = 0.9 m and mass M = 1.4 kg is sitting on a frictionless table. A top view of the puck is shown in the figure. Three constant forces are applied to the puck as shown: F1 = 3.1 N and F2 = 4.9 N are applied at radius R1, while F3 = 3.6 N is applied at radius R2 = 0.3 m. The moment of inertia for the puck is I =1/2 MR12.

What is the angular acceleration of the puck in rad/s2?
