How do i find the distance something will travel if I have the energy potential?

A spring has a constant force of 600.0N/m. This spring is used to shoot a 25g ball straight up after the spring is compressed 25.0cm. How high will the ball travel assuming all energy is transferred to the ball.



I have found the energy potential to be 18.75J but what do i do next to find the distance the ball will travel?How do i find the distance something will travel if I have the energy potential?You have calculated the enrgy transferred by the spring to the ball.



This energy will appear as potential energy in the ball = m x g x h



So h = 18.75 / (0.25 x 9.81) = 7.65 mHow do i find the distance something will travel if I have the energy potential?For straight up, the potential energy in the spring is the same as the potential energy at the peak height, with the formula E = mgh, h being the height at maximum.
