Homework Help: Physics

Posted by Sarah on Sunday, December 11, 2011 at 1:06pm.

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 5 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)
