Задача 40452.

At the initial moment of time, the displacement of the oscillating material point is maximum and equal to 8 cm. For 5 oscillations, the amplitude decreases by 25 percent of its original value. Oscillation period 0.5 s. Determine the damping coefficient, the logarithmic damping decrement and write the equation for the oscillations of a material point.

A detailed solution with a brief note of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have any questions about the solution, write. I try to help.
