A block with a mass of 0.30 kg is attached to a horizontal spring. The block is pulled back from its equilibrium position until the spring exerts a force of 1.0 N on the block. When the block is released, it oscillates with a frequency of 1.5 Hz. How far was the block pulled back before being released?
A small earthquake starts a lamppost vibrating back and forth. The amplitude of the vibration of the top of the lamppost is 6.7 cm at the moment the quake stops, and 8.4 s later it is 1.5 cm.
A. What is the time constant for the damping of the oscillation?
B. What was the amplitude of the oscillation 4.2 s after the quake stopped?
