Need Help Not the Answer Please!
A toy cannon uses a spring to project a 5.30-g rubber ball. The spring is originally compressed by 5.00 cm and has a force constant of 8.00 N/m. When the cannon is fired, the ball moves 15.0 cm through the horizontal barrel, and there is a constant force of 0.0320 N between the barrel and the ball.
(a) With what speed does the projectile leave the barrel of the cannon?
(b) At what point does the ball have maximum speed?
(c) What is the maximum speed?
Right now my class is dealing with potential energy and this is the first class for Physics for Engineers. I already solved letter (a) but I need help with (b) and (c). I was going to use the derivative to solve for (b) since the keyword is maximum, but I don't know if that's correct. Any advice on approaching this problem would be great. Don't worry it's not an exam question just a problem assigned from the book:)
