A mass weighing 1 lb is attached to a spring whose spring constant is 1.5 lb/ft. The medium offers a damping force that is numerically double the instantaneous velocity. The mass is released from a point 10 cm above the equilibrium position with a downward velocity of 2.3 m/s, Determine: 1. Time it takes for the object to pass through the equilibrium position. 2. Time in which the object reaches its extreme displacement from the equilibrium position. 3. What is the position of the mass at the instant calculated in part 2? 4. Graph the movement.
