Question

A spring-loaded launcher is used to shoot a ball of mass 1.50 kg straight up in the air, as shown in (Figure 1). 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 hmax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of the m = Which of the following statements are true? Check all that apply. View Available Hint(s) launcher. Assume that all movement occurs in a straight. Mechanical energy is conserved because no dissipative forces perform work on the ball. Figure 1 of 1 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 launcher. Submit hmax y 0 Part B 0) Find vm , the launch velocity (i.e. the velocity of the ball at the spring's equilibrium position y View Available Hint(s) VAD ?
