Homework Help: physics-energy

Posted by nate on Friday, February 19, 2010 at 11:34am.

A toy gun uses a spring to project a 5.3 g soft rubber sphere vertically. The spring constant is 8.0 N/m, the barrel of the gun is 15 cm long, and a constant frictional force of 0.032 N exists between barrel and projectile. How high does the projectile go if the spring was compressed 5.0 cm for this launch? For this, I need the problem solved step by step.
