A toy cannon uses a spring to project a 5.26-g soft rubber ball. The spring is originally compressed by 5.09 cm and has a force constant of 8.05 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 9 N on the ball.
(a) With what speed does the projectile leave the barrel of the cannon?(b) At what point does the ball have maximum speed?(c) What is this maximum speed?
