Answer:
0.091 sec
Explanation:
f = frequency of oscillation of the mass attached to the spring = 11 Hz
T = Time period of oscillation of the mass attached to the spring = ?
Time period and frequency of oscillation of the mass attached to the end of spring are related as
[tex]T = \frac{1}{f}[/tex]
Inserting the values
[tex]T = \frac{1}{11}[/tex]
T = 0.091 sec
