Solution: In a physics lab experiment, a compressed spring launches a 31 g metal ball at a 35° angle. Compressing the spring 18 cm causes the ball to hit the floor 1.8 m below the point at which it leaves the spring after traveling 5.6 m horizontally. What is the spring constant?

In a physics lab experiment, a compressed spring launches a 31 g metal ball at a 35° angle. Compressing the spring 18 cm causes the ball to hit the floor 1.8 m below the point at which it leaves the spring after traveling 5.6 m horizontally. What is the spring constant?
