The light pulley hangs from the ceiling on a spring with a force constant k. The block “m” hangs from an ideal string.
- Find the period of low-amplitude vertical vibrations of the system shown.
- Find the maximum amplitude of oscillations if motion of the block remains SHM.
- If the block is released when the spring is initially unstarched. Write the displacement from its initial position as function the time treating downward direction as positive.
- none
The correct answer is: none
