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
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.
