Question

A small spring-loaded launcher is designed to fire steel ball bearings with masses of 0.26 kg . When setting the launcher, you compress the spring a distance of 15 cm. You then fire the launcher straight up and find that the projectiles reach a maximum height of 1.3 mm above the point that they leave the launcher. You load another ball bearing, compress the spring a distance of 20 cm, and place it horizontally at the edge of a table that is 0.8 mm tall.

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