The 2-lb collar is released from rest at A and slides freely down the inclined rod, striking the stop at B with a velocity v. The spring of stiffness 1.6 lb/ft has an unstretched length of 13 inches. a) Calculate the velocity v, b) if u=0.1, calculate the work done by the friction between the rod and the collar, recalculate the speed and efficiency.
