DESCRIPTION
Task 40539.
The equation of damped oscillations of a material point with a mass of 20 g has the form: x = 4 * 10 ^ -2 * e ^ (- 0.2t) * cos (pt / 4), m. Determine: coefficient of elasticity, coefficient of resistance, natural frequency of vibrations, logarithmic decrement of attenuation and amplitude of oscillations after two complete oscillations.
