physics and guns
posted by Lauren .
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  cm, and it takes a force of 9.12 N to compress the spring to that point. (a) If the gun is red vertically, how fast (m/s) is the pellet moving when it loses contact with the spring? (b) To what maximum height (m) will the pellet rise? (as measured from the original latched position)
