76. Ball mass m = 10 kg, and the radius R = 20 cm is rotated about an axis passing through its center. The equation of the rotation of the ball has the form φ = A + Vt2 + St3, where B = 4 rad / s2; C = -1 rad / c3. Find the change in the torque acting on the ball. Determine the torque M at time t = 2c.
