Engineering Mechanics - Dynamics Chapter 14 Problem 14-66 The collar has mass M and rests on the smooth rod. Two springs are attached to it and the ends of the rod as shown. Each spring has an uncompressed length l . If the collar is displaced a distance s = s' and released from rest, determine its velocity at the instant it returns to the point s = 0. Given: M 20 kg = k 50 N m = s' 0.5 m = k' 100 N m = l 1m = d 0.25 m = Solution: T 1 0 = V 1 1 2 kk ' + () s' 2 = T 2 1 2 Mv 2 = V 2 0 = 0 1 2 ' + s' 2 + 1 2 c 2 0 + = v c ' + M s' = v c 1.37 m s = Problem 14-67 The collar has mass
