Question 725848
the length of a pendulum is directly proportional to the square of the time it takes for the pendulum to make one complete swing.
L = k*t^2
------------------------
if a 20 inch long pendulum takes about 5 seconds to swing through one complete cycle
20 = k*5^2
k = 4/5
----
then find the model that relates the length L of the pendulum to the time period T of the pendulum
------
Equation for that pendulum:
L = (4/5)t^2
