A 3.5 kg rock is on a spring launcher pointed vertically into the sky. It has a spring constant of 400 N/m and is compressed by 0.25 m. a. What was the potential energy of the launcher before it was released? b. What is the kinetic energy of the rock just after it was released? c. What is the maximum velocity of the rock? d. What is the gravitational potential energy of the rock at its highest point? e. How high did the rock go?
