A toy cannon uses a spring to project a 5.35-g soft rubber ball. The spring is originally compressed by 4.96 cm and has a force constant of 8.02 N/m. When the cannon is fired, the ball moves 15.8 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? Make certain you have correctly converted all of the centimeter and gram quantities to MKS units. m/s (b) At what point does the ball have maximum speed? What is the sign of the acceleration an instant before the velocity reaches a maximum and an instant after the velocity reaches its maximum? cm (from its original position) (c) What is this maximum speed? Note that the initial potential energy of the spring is now found in several different forms. Make certain you can list each of them before writing down an energy equation. m/s
