A. At the end of a horizontal spring of constant k = 400 N / m, the object is mass m = 100g and performs a simple harmonic movement. When the object is in position x = 0.016 m from the equilibrium position, it has a speed of 0.2m / s. Find: (a) the period of oscillation, (b) the amplitude of the oscillation, and (c) the maximum velocity of the mass m.
B. A vertical spring is provided in which a mass of mass m = 3kg hangs. We divert the spring from the equilibrium position, leave it free and begin to perform a simple harmonic motion, with an oscillating period of 0.6 s. Calculate: (a) the spring constant, (b) how long the spring stretches when the weight is in the equilibrium position? Given that g = 9.8 m / s2.
