The block, whose mass m = 2.0 kg can be considered uniformly distributed along the rim, rotates with an initial frequency n0 = 12 rpm. The diameter of the block is D = 30 cm. Determine what moment of force must be applied to the block so that it, moving uniformly slow, stops within Δ t = 8.0 s. How many revolutions will it make before stopping?
