A spring has an unstretched length of (20 mathrm{~cm}). A (100 mathrm{~g}) mass hanging from the spring
Question:
A spring has an unstretched length of \(20 \mathrm{~cm}\). A \(100 \mathrm{~g}\) mass hanging from the spring stretches it to an equilibrium length of \(30 \mathrm{~cm}\).
a. Suppose the mass is pulled down to where the spring's length is \(40 \mathrm{~cm}\). When it is released, it begins to oscillate. What is the amplitude of the oscillation?
A. \(5.0 \mathrm{~cm}\)
B. \(10 \mathrm{~cm}\)
C. \(20 \mathrm{~cm}\)
D. \(40 \mathrm{~cm}\)
b. For the data given above, what is the frequency of the oscillation?
A. \(0.10 \mathrm{~Hz}\)
B. \(0.62 \mathrm{~Hz}\)
C. \(1.6 \mathrm{~Hz}\)
D. \(10 \mathrm{~Hz}\)
c. Suppose this experiment were done on the moon, where the free-fall acceleration is approximately \(1 / 6\) of that on the earth. How would this change the frequency of the oscillation?
A. The frequency would decrease.
B. The frequency would increase.
C. The frequency would stay the same.
