Homework Help: Physics- spring gun

Posted by Ramsey on Monday, June 6, 2011 at 2:36am.

A spring gun is made by compressing a spring in a tube and then latching the spring at the compressed position. A 4.97-g pellet is placed against the compressed and latched spring. The spring latches at a compression of 3.92 cm and it takes a force of 9.12 N to compress the spring to that point.

If the gun is fired vertically, how fast (m/s) is the pellet moving when it loses contact with the spring?
