A toy cannon uses a spring to project a 5.30 -g soft rub- ber ball. The spring is originally compressed by $5.00 \mathrm{cm}$ and has a force constant of $8.00 \mathrm{N} / \mathrm{m} .$ When the cannon is fired, the ball moves $15.0 \mathrm{cm}$ through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of $0.0320 \mathrm{N}$ 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?

A toy cannon uses a spring to project a $5.30-\mathrm{g}$ soft rubber ball. The spring is originally compressed by $5.00 \mathrm{~cm}$ and has a stiffness constant of $8.00 \mathrm{~N} / \mathrm{m}$. When it is fired, the ball moves $15.0 \mathrm{~cm}$ through the barrel of the cannon, and there is a constant frictional force of $0.0820 \mathrm{~N}$ between the barrel and 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?
