Answer to Question #33344 in Mechanics | Relativity for ahmedmagedhussein
A toy cannon uses a spring to project a 5.39-g soft rubber ball. The spring is originally compressed by 4.99 cm and has a force constant of 8.03 N/m. When the cannon is fired, the ball moves 14.9 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.031 3 N on the ball. At what point does the ball have maximum speed?
