Ok here's the problemo: | |ooooo[m1]00000[m2] | I have two masses attached to two springs, the "ooo"s are the springs, and the "[m]"s are the masses, the spring constants are the same , and so are the masses. I know to do the problem, the only thing is I am having trouble figuring out the equations of the forces on the two masses. I thought [tex] F_1 = -kx_1 + k(x_2 - x_1) , F_2 = kx_1 - kx_2 [/tex] where [tex] x_1 [/tex] is the displacement to the right from [tex] m_1 [/tex] and [tex] x_2 [/tex] is the displacement to the right from [tex] m_2 [/tex]
You probably need some unstretched lengths in there somewhere otherwise your masses are going to be beating against the wall and each other.
