Springs AB and CD have a stiffness of ka = 8 lb/in and kçp = 4 lb/in, respectively, and both springs have an un-stretched length of 12 in. If the 5-lb collar BC is suddenly released from rest in the position shown, determine how far the collar travels to the left before it momentarily comes to rest. Take the coefficient of kinetic friction between the collar 30 B 14 in 10 in and guide rod AD as 4, = 0.3.
