Chapter 3, Problem 45(choose chapter or problem)
The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. Find the period when the length is 121 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 6 seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
