A toy cannon uses a spring to project a 5.40-g soft rubber ball. The spring is originally compressed by 4.91 cm and has a force constant of 7.95 N/m. When the cannon is fired, the ball moves 14.1 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.031 O N on the ball. (a) With what speed does the projectile leave the barrel of the cannon? 1.389 m/s (b) At what point does the ball have maximum speed? cm (from its original position) (c) What is this maximum speed? m/s
