The collar has a mass M and is supported on the rod having a coefficient of kinetic friction μ_k. The attached spring has an unstretched length l and a stiffness k. Determine the speed
of the collar after the applied force F causes it to be displaced a distance s = s₁ from point A. When s = 0 the collar is held at rest.
