A ball with a mass of #256 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 #4/3 m# when the ball was released. How high will the ball go?

8,5 m
Explanation:
the final potential energy of the ball is the same of the elastic initial energy of the spring. Espring = 1/2 K X^2 = 1/2 x 24 x 16/9 = 21,3 J = E potential = mgh
h=E/mg = 21,3/(0,256 x9,8) = 8,5 m
