Physics Olympiad #010 [Oscillation of the spring-blocks system]

The system depicted below is in equilibrium; the right spring is stretched a distance x1. The coefficient of friction between the two blocks is μ s, and there is no friction between the block and the floor. The spring constants are 3k and k respectively. The mass of the two blocks is m. Determine the maximum deviation of the system oscillations where the upper block is still at rest relative to the bottom block. The mass of the spring can be ignored.
