A toy cannon uses a spring to project a 5.31-g soft rubber ball. The spring is originally compressed by 4.90 cm and has a force constant of 8.09 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 7 N on the ball.
Required:
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?
