A thread with loads of masses 50 g and 60 g tied to its ends is thrown over a block with a diameter of 4 cm. Determine the moment of inertia J of the block if, under the action of gravity of the loads, it received an angular acceleration of 1.5 rad / s^2. Ignore friction and slippage of the thread on the block.

A detailed solution with a brief note of the condition, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
