A small spring-loaded launcher is designed to fire steel ball bearings with masses of 0.24 kg . When setting the launcher, you compress the spring a distance of 12 cm . You then fire the launcher straight up and find that the projectiles reach a maximum height of 1.2 m above the point that they leave the launcher. You load another ball bearing, compress the spring a distance of 19 cm , and place it horizontally at the edge of a table that is 0.6 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?
