A toy cannon uses a spring to project a 5.20-g soft rubber ball. The spring is originally compressed by 4.91 cm and has a force constant of 7.99 N/m. When the cannon is fired, the ball moves 14.4 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.031 1 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
