2. Same as in problem 1 above, but let us now assume there are no damping forces

anymore. However, the left mass is now driven by a driving force F.cos(2wt), and the

right mass has a driving force 2F, cos(2wt), where w is the square root of k/m. Find

the particular solution for the positions of the masses as functions of time. Explain

why your answer makes sense.
