g A toy cannon uses a spring to project a 5.20-g soft rubber ball. The spring is originally compressed by 4.99 cm and has a force constant of 7.97 N/m. When the cannon is fired, the ball moves 15.4 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.032 2 N on the ball. (a) With what speed does the projectile leave the barrel of the cannon
