If they arepulled back to the position shown and released from rest, determine the maximum height thepellet of mass Mwill reach if it is fired vertically upward. Neglect the mass of the rubber bandsand the change in elevation of the pellet while it is constrained by the rubber bands. Each rubberband has a stiffness k.Given:
