A spring-loaded toy gun projects a 5.0 g nerf pellet horizontally. The spring constant is 8.5 N/m, the barrel of the gun is 12 cm long, and a constant frictional force of 0.029 N exists between the barrel and the nerf pellet. If the spring is compressed 5.5 cm for this launch, determine the speed (in m/s) of the pellet as it leaves the barrel. (Assume the pellet is in contact with the barrel for the full length of the barrel.)
