The cylinder has a weight of 20 lb and is pushed against a series of Belleville spring washers so that the compression in the spring is s = 0.05 ft. If the force of the spring on the cylinder is where s is given in feet, determine the speed of the cylinder just after it moves away from the spring, i.e., at s = 0.
