77. Wheel radius R = 0,1m rotated so that the angular velocity of the time given by the equation ω = 2At + 5Bt4 (A = 2 rad / s2 and B = 1 rad / C5). Determine the total acceleration of the points of the wheel rim at t = 1 s after the start of rotation and number of revolutions made by the wheel during this time.
