Question

A small spring-loaded launcher is designed to fire steel ball bearings with masses of 0.3 kg . When setting the launcher, you compress the spring a distance of 13 cm . You then fire the launcher straight up and find that the projectiles reach a maximum height of 0.9 m above the point that they leave the launcher. You load another ball bearing, compress the spring a distance of 17 cm , and place it horizontally at the edge of a table that is 0.5 m tall.

You fire the ball from the edge of the table. How far from the base of the table does it hit the ground?
