Child A applies a force of 30N tangent to the edge of the disc to cause it to rotate counter clockwise. Child B also applies a force of 20N tangent to the edge of the disc to cause it to counter clockwise. The net torque applied to the disc causes an angular acceleration of 8.33rad/s^2. a) What is the moment of inertia of the solid plastic disc?
