The spring has spring constant k= 667 N/m If the spring is compressed a distance of 25.0 centimeters from its equilibrium position y 0 and then released, the ball reaches a maximum height h (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of the gun. Assume that all movement occurs in a straight line up and down along the y axis Part A Which of the following statements are true? Check all that apply View Available Hint(s) Mechanical energy is conserved because no dissipative forces perform work on the ball The forces of gravity and the spring have potential energies associated with them. No conservative forces act in this problem after the ball is released from the spring gun.
