Homework Help: Two damped pendulums with different masses.

  1. Mar 17, 2010 #1
    Two simple pendulums with the same length L but different masses, m1 and m2=2*m1, are set swinging at the same time with the same initial amplitude. Both pendulums are damped by the same force, Fdamp=-[tex]\gamma[/tex]s(dot). Eventually, the amplitude of the lighter pendulum decreases to half its initial value.
    [tex]\gamma[/tex]




    I have found the equation [tex]\frac{A(t)}{Ao}[/tex]=e(-[tex]\gamma[/tex]t/2m), however I am not sure how to apply it correctly.

    What do you need to find in the first place?
