Consider the system of two masses and three springs shown in the figure
and the following masses and spring constantsFind the general solution of the above system using the given masses and spring constants by solving the system and applying the initial conditions
I got the roots -10 and 1 from r^2+9x-10 and then when I solve for the constants I am getting the wrong answer. DId I get the wrong roots or am I going wrong solving for the constants?
with the following equations of motion:m1x
=−(k1+k2)x+k2y
m2y
=k2x−(k2+k3)y
m1=4
m2=4
k1=4
k2=8
k3=4
x(0)=A
, x
(0)=B
, y(0)=C

(0)=D
