Solving a problem in physics section 22 point 82 mechan

82. The disc of radius R = 5 cm is rotated around a fixed axis so that the angular velocity dependence of the time given by the equation ω = 2At + 5Bt4 (A = 2 rad / s2, V = 1 rad / c5). Determine for points on the rim of the disc at the end of the first second after the beginning of movement: 1) full acceleration; 2) the number of revolutions made by the drive.
