11.4.12
Does the disk rotate uniformly accelerated around the Oz axis with angular acceleration? = 2 rad / c2. At what speed should the M point move uniformly along the rim of the disk, so that at the time t = 1c the Coriolis acceleration of this point is 20 m / s2 if the initial angular velocity of the disk is 3 rad / s. (Answer 2)
