Question

How would you decrease the period of the spring whose motion is shown in the graph?

A. Increase the initial displacement of the spring.
B. Increase the mass hanging from the spring.
C. Decrease the initial displacement of the spring.
D. Decrease the mass hanging from the spring.

Answer 1

The period of a spring can be described by the formula T = 2pi(sqrt(m/k)), where T is the period in seconds, m is the mass in kg, and k is the spring constant in N/m. Therefore, if the mass decreases, the period of the spring must decrease because they are proportional.
