# Identical Mass-Springs with Different Displacement#

Two identical springs are attached to two identical masses. Both masses are free to slide along a frictionless horizontal surface. One of the springs is displaced a distance $$d$$ from its equilibrium position, while the other is displaced a distance $$2d$$.

## Part 1#

If both masses are released at the same instant, which of the springs, A or B, returns to its unstretched length first?
