: The period of a simple pendulum is directly proportional to the square root of its length, If a pendulum has a length of 6 feet and a period of 2 seconds, to what length should it be shortened to achieve a 1 second peroid? Ok my answer is 3 feet but the question seems to have more to it I think. Thanks for checking this answer.

The period of a simple pendulum is directly proportional to the square root of its length.
period = T
length= L
where k is a constant of proportionality.
to work out what k is, rearrange the equation above:
originally,
T=2
L=6
this gives
So now we can write
we want T to be 1, so:
L=3/2 ft.
I hope this helps
P.S. I am trying to start up my own homework help website. I would be extremely grateful if you would e-mail me some feedback on the help you received to adam.chapman@student.manchester.ac.uk
