The solution of the problem 1.6 cr 1 from the problem b

Task 1.6
A solid ball weighing 1 kg and a radius of 5 cm rotates about an axis passing through its center. The law of rotation of the sphere is expressed by the equation φ = 10 + 5t - 2t2. At a point farthest from the axis of rotation, a force tangent to the surface acts on the ball. Determine this force and the braking moment.
