A toy cannon uses a spring to project a 5.31-g soft rubber ball. The spring is originally compressed by 4.97 cm and has a force constant of 8.09 N/m. When the cannon is fired, the ball moves 15.1 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?

(b) At what point does the ball have maximum speed?

cm (from its original position)

m/s
