Question

A simple pendulum has frequency of 2 Hz. How long does it take to move from mean to extreme

position:

a. 0.12 s b. 0.2 s

c. 0.5 s d. 0.05 s

​

Answer 1

Answer:

A 2Hz pendulum is said to have a “quarter second beat”. That is the time to move from one extremum to the other. The motion is near, whose root mean square amplitude is 0.7071 and whose mean (average) amplitude is zero if its peak amplitude is 1.
