A toy cannon uses a spring to project a5.30 g soft rubber ball. The spring isoriginally compressed by 5.00cm and has a force constant of 8.00 N/m. Whenthe cannon is fired, the ball moves 15.0 cm through the horizontal barrel of the cannon andthe barrel exerts a constant friction force of 0.0320 N on the ball.
(a) With what speeddoes the projectile leave the barrel of thecannon?
(b) At what point does the ball havemaximum speed?
(c) What is this maximum speed?

*Please explain how your solving and what formulas you use also,I'm new to physics. Thank you.
