    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 4.07 cm, and it takes a force of 9.12 N to compress the spring to that point. (a) If the gun is fired vertically, how fast is the pellet moving when it loses contact with the spring? (Include the effect of...
