A simple pendulum oscillates with frequency f.
(a) What is its frequency if the entire pendulum accelerates at
2/3g upward?
_____________ f
(b) What is its frequency if accelerates at
0.666666666666667g downward?
_____________ f
frequency of the pendulum is given by
(a) given the pendulum accelerates at (2/3)g upward.
Therefore, the effective gravity is
The new frequency of th pendulum is
If the pendulum accelerates at (2/3)g upward then its frequency is 1.291f
(b) given the pendulum accelerates at 0.66666666667g downward
here 0.666666666667g is approximated as 0.667g
Therefore, the effective gravity is
The new frequency of th pendulum is
If the pendulum accelerates at 0.667g downward then its frequency is 0.577f
