Answer #1

From the conservation of energy

Initial elastic potential energy = Final gravitational potential energy

there fore 24 J = mgh

height above the equilibrium point h = 24/mg = 24/(.270*9.8) = 9.07 meters

    9. A spring-loaded toy gun is used to shoot a ball of mass m-2.50 kg straight up in the air, as shown below. The spring has spring constant k-500 NI/m. If the spring is compressed a distance of 20.0 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 gun. Assume that...

    A hockey puck of mass m = 0.170 kg is loaded into a spring gun with spring constant k = 306 N/m. The spring is compressed by a distance d = 0.100 m and then released, launching the puck onto a horizontal and frictionless surface of ice with speed v in the positive x-direction. This puck then collides with another puck of the same mass which is at rest at the origin. After the collision the two pucks move away...
