**Henry**, Wednesday, January 1, 2014 at 8:37pmIf L is known:

1. Plug-in the value of L.

2. Simplify the quantity under the radical.

3. Take the square root of the number

under the radical.

Example:

L = 19.6 m.

Solve for T.

T = 2pi*sqrt((2/3)*L/g)

T = 6.28*sqrt((2/3)*19.6/9.8) =

6.28*sqrt((2/3)*2) = 6.28*sqrt((4/3) =

6.28 * 1.1547 = 7.25 s.
