Projectile Motion

Question

A toy cannon uses a spring to project a $$5.30-g$$ soft rubber ball. The spring is originally compressed by $$5.00\ cm$$ and has a force constant of $$8.00\ N/m$$ When the cannon is fired, the ball moves $$15.0\ cm$$ through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of $$0.0320 N$$ on the ball. At what point does the ball have maximum speed?
