A toy cannon uses a spring to project a 5.38-g soft rubber ball.The spring is originally compressed by 4.91 cm and has a forceconstant of 8.08 N/m. When the cannon is fired, the ball moves 15.6cm through the horizontal barrel of the cannon, and the barrelexerts a constant friction force of 0.032 6 N on the ball.
(a) With what speed does the projectile leave the barrel of thecannon? m/s
(b) At what point does the ball have maximum speed? cm (from itsoriginal position)
(c) What is this maximum speed? m/s
