Math Problem Statement
The period of a pendulum is the time it takes the pendulum to make one full swing back and forth. The period T, in seconds, is given by the formula
Upper T equals 2 pi StartRoot StartFraction Upper L Over 32 EndFraction EndRootT=2πL32,
where L is the length, in feet, of the pendulum. Suppose a pendulum used to show the rotation of the earth has a period of approximately
16.216.2
seconds. What is its length? Use
3.143.14
for
piπ.
