A toy cannon uses a spring to project a 5.22-g soft rubber ball. The spring is originally compressed by 5.09 cm and has a force constant of 8.07 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 0.031 0 N on the ball. (a) With what speed does the projectile leave the barrel of the cannon? 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 A toy cannon uses a spring to project a 5.22-g soft rubber ball.
