So I am an engineer and its been about two years since I have taken a differential equations class and the method in which to solve this has totally been lost to me. If anyone can help me out that would be great thanks. m1x1''+k(x2-x1)+b(x2'-x1')+F(t)=0 m2x2''+k(x1-x2)+b(x1'-x2')=0 I need to solve for x1 in terms of all over variables. Here m1,m2,k,and b are constant. F(t) is some impulse force on the system. This is suppose to model a 2 mass spring damper system with an impulse force on one of the masses.
