2. Collars A and B move freely along the frictionless, vertical poles. Initially, collar A is at rest (VA = 0) and collar B has a constant velocity of 6 in/s downward. Collar A accelerates downward at a constant rate.. Knowing that collar A moves 18 inches in the first three seconds, determine and plot the velocity of the weight for t = 0, 1, 2, 3, 4, 5s. Find the net distance the weight moves in the first five seconds. A O W OB
