A load of mass m = 3 kg is suspended from a spring with a stiffness coefficient c = 300 N / m and is in free straight vertical oscillatory motion. Determine the amplitude of the load's oscillations in cm if, at the time t0 = 0, its velocity v0 = 2 m / s, and the displacement from the static equilibrium position x0 = 0.3 m (Answer 36.1)
