Reference no: EM13608865

A toy cannon uses a spring to project a 5.39-g soft rubber ball. The spring is originally compressed by 4.93 cm and has a force constant of 7.96 N/m. When the cannon is fired, the ball moves 15.9 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?
