Could anybody provide some guidance or steps for this physics problem? It would be much appreciated?
I know that this is a pendulum, and that the formula T = 2pi (L/g)^(1/2) can probably be used. I tried the following:
Exponential 1/2 = square root of L/g
L = 0.5 times (0.256) <-- cm to m
g = 9.8
Neither the width nor the mass matter as they do no appear in the formula
The answer is supposed to be 0.829 sec
Any advice on where I went wrong?
If either of these are the correct formula, I am not sure how to use them, particularly with I and θ
