Answer: Period = 13.15 s
Solution:
The period of a pendulum is the time of pendulum takes to swing back and forth.
Function
Where,
L is length of pendulum in feet
T is time of pendulum in seconds
We have to calculate the time of pendulum whose length is 140 feet.
So, we substitute L=140 into formula and to solve for t
We get t,
s
Period = 13.15 s
