Homework Statement
A rod suspended on its end and acting as a physical pendulum swings with a period of 2.24 s. What is its length? (g = 9.80 m/s2)
Homework Equations
T=2(pi) * (sqrt)(L/G)
The Attempt at a Solution
Okay, so I'm given the period, which is 2.24 seconds.
I'm also given G, as it's 9.8.
I plug in the values and the resulting equation is what I get:
2.24=2pi * (sqrt)(L/9.8)
I divide 2.24 by 2pi, which leaves me with this:
.356507=(sqrt)(L/9.8)
I square both sides and get:
.127097=L/9.8
Multiply 9.8 * .127097 should give me L.
I get L=1.24555. I put it into my online homework assignment, and it's wrong.
What am I doing incorrectly?
