The 20kg collar is supported on a rough rod and attached to two springs, with its spring stiffness of  k1 = 15 N/m and k2 = 25 N/m. The collar is initially at rest when d = 0.4 m, where both springs are in undeformed condition. By using the Principle of Work and Energy, determine

The total work done by the collar when and applied force of F = 120 N causes the collar to be displaced such that d = 0.25 m, and the coefficient of kinetic friction between the rod and the collar is  

The final speed of the collar
