Each of the two elastic rubber bands of the slingshot has an unstretched length l. If they are pulled back to the position shown and released from rest, determine the speed of the pellet of mass M just after the rubber bands become unstretched. Neglect the mass of the rubber bands and the change in elevation of the pellet while it is constrained by the rubber bands. Each rubber band has a stiffness k.
