A ball with a mass of #480 g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #24 (kg)/s^2# and was compressed by #8/9 m# when the ball was released. How high will the ball go?
If Spring compressed by
After Release spring loaded contraption Potential Energy Changes into Kinetic Energy. (Conservation of Energy)
Hence Mass of 480g has Kinetic Energy
Now Using Conservation of Energy
