If its spring is compressed a distance of 0.180 m and the gun fired vertically as shown, the gun can launch a 19.0 g projectile to a maximum height of 22.0 m above the starting point of the projectile. Neglecting all resistive forces, determine the spring constant.Neglecting all resistive forces, determine the speed of the projectile as it moves through the equilibrium position of the spring (where x = 0)
