Question
A visitor to a lighthouse wishes to determine
the height of the tower. The visitor ties a
spool of thread to a small rock to make a
simple pendulum, then hangs the pendulum
down a spiral staircase in the center of the
tower. The period of oscillation is 9.71 s.
What is the height of the tower? The accel-
eration due to gravity is 9.81 m/s2 .
Answer in units of m

Period = 2*pi*sqrt(L/g)
Solve for L, the pendulum length and tower height.
You expact you to assume the pendulum string is attached near the top of the tower.
