Problem 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.
