Homework Help: Help rearranging this equation.

    1. The problem statement, all variables and given/known data
    On the construction site for a new skyscraper, a uniform beam of steel is suspended from one end. If the beam swings back and forth with a period of 5.00 , what is its length?

    I know the equation I need to use but I'm having trouble rearranging it to solve for Length (L).

    2. Relevant equations

    3. The attempt at a solution
    I tried to rearrange the equation to solve for L and got this.

    any help would be great!

    Why not simply square both sides of the original?

    You know all the other values. Plug them in.
