The body rotates around a fixed axis according to the law phi \u003d A Bt Ct ^ 2, where A \u003d 10 rad, B \u003d 20 rad / s, C \u003d -2 rad / s ^ 2. Find the total acceleration of a point located at a distance R = 0.1 m from the axis of rotation at the time t = 4 s.
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.
