A 4 kg mass is attached to a spring with spring constant 6 Nt/m. What is the frequency of the simple harmonic motion? 1.224 What is the period? 5.138 seconds radians/second Suppose the mass is displaced 0.5 meters from its equilibrium position and released from rest. What is the amplitude of the motion? [0.5 meters Suppose the mass is released from the equilibrium position with an initial velocity of 0.5 meters/sec. What is the amplitude of the motion? 0 meters Suppose the mass is is displaced 0.5 meters from the equilibrium position and released with an initial velocity of 0.5 meters/sec. What is the amplitude of the motion? What is the maximum velocity? meters m/s
