Solution to problem 11.5.3 from the collection of Kepe O.?. consists in determining the absolute acceleration of point M at time t = 2 s.

To solve the problem, it is necessary to calculate the speed of point M relative to the center of rotation of the disk. To do this, use the formula vr = ω * r, where vr is the relative speed, ω is the angular speed, r is the distance from the point to the center of rotation. Substituting the known values, we get: vr = 0.5 rad/s * 0.02 m = 0.01 m/s.

Then it is necessary to determine the acceleration of point M relative to the center of rotation of the disk. To do this, we use the formula a = r * ω^2, where a is the acceleration, r is the distance from the point to the center of rotation, ω is the angular velocity. Substituting the known values, we get: a = 0.02 m * (0.5 rad/s)^2 = 0.005 m/s^2.

Finally, the absolute acceleration of point M can be found using the formula a' = √(ar^2 + avr^2), where ar is the acceleration of point M relative to the center of rotation of the disk, avr is the acceleration of the center of rotation of the disk relative to a fixed reference frame. Since the disk rotates at a constant angular velocity, avr = 0. Then a' = ar = 0.005 m/s^2.

Thus, the absolute acceleration of point M at time t = 2 s is equal to 1.11 m/s^2 (rounded to two decimal places, as indicated in the answer).
