Question: 405

3. A student observes that a block oscillating on the end of a spring with an amplitude of 20 cm has a period 0.25 s. What is the period of the same oscillating block if the amplitude is increased to 60 cm ?

  • A. 0.25 s
  • B. 0.75 s
  • C. 1.5 s
  • D. Cannot be determined

Correct Answer: A

Explanation:

A

The frequency of the block attached to a spring is given by the equation . Changing the amplitude will not affect the period of the oscillations.
