Question
Transcribed Image Text:A toy cannon uses a spring to project a 5.28 - g soft rubber ball. The spring is originally compressed by 5.04 cm and has
a force constant of 8.04 N/m. When the cannon is fired, the ball moves 14.5 cm through the horizontal barrel of the
cannon, and the barrel exerts a constant friction force of 0.031 0 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
