Homework Statement
A simple Pendulum is suspended from the ceiling of an elevator. The elevator is accelerating upwards with acceleration a. The period of this pendulum, in terms of its length L, g, and a is:
2[tex]\pi[/tex]*(L/a)^(1/2)
OR
2[tex]\pi[/tex]*(L/(g+a))^(1/2)
OR
2[tex]\pi[/tex]*(L/g)^(1/2)
Homework Equations
T = 2[tex]\pi[/tex]*(L/g)^(1/2)
The Attempt at a Solution
Not sure where to start. It doesn't seem like there's really math involved here. I tried drawing a free body diagram, but that made things worse. I'm pretty sure it's the middle one, because the other 2 just don't make sense, because the formula needs to both a and g into account, right?
