Spring-loaded toy gun projects a 5.9 g nerf pellet horizontally. the spring constant is 8.5 n/m, the barrel of the gun is 17 cm long, and a constant frictional force of 0.037 n exists between the barrel and the nerf pellet. if the spring is compressed 6.8 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.) m/s
