A ball with a mass of #400 g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #25 (kg)/s^2# and was compressed by #3/7 m# when the ball was released. How high will the ball go?

Potential Energy stored in spring if it compressed by x meter
where k
if spring release the ball will get kinetic energy which is equal to the potential energy of spring. (Conservation of energy)
To find the height we use Newton's Equation
where
Hence
