The disk at the initial moment rotates according to the equation f= At^3 Bt^2, where A = 20 rad/s^3, B = 18 rad/s^2. Calculate the angular velocity, angular acceleration, total acceleration a of a point located at a distance r = 0.1 m from the disk axis, after a time t = 0.1 s after the start of rotation.
