A Question 5 (1 point) Retake question m v1²+ Fdx = 1/2m v2² Fdx → mgh; µµNd; ½kx² 3 things to keep track of, friction, spring, and mgh. K Your Answer: Jo. An 48-lb collar is released from rest in the position shown, slides down the inclined rod, and compresses the spring. The direction of motion is reversed and the collar slides up the rod. Knowing that the maximum deflection of the spring is 5 in., determine the maximum speed of the collar. Let theta = 35°, L = 24 in, and k = 46 lb/ft. (hint, you will need to find the coefficient of kinetic friction between the collar and the rod in order to find vmax) Answer C
