A toy cannon uses a spring to project a 5.24 gram soft rubber ball. The spring is originally compressed by 4.95 centimeter and has a force constant of 7.94 N/m. When the cannon is fired, the ball moves 14.1 centimeter through the horizontal barrel of the cannon, and there is a constant frictional force of 0.0316 Newton between the ball and the barrel.
(a) Find with what speed does the projectile leave the barrel of the cannon?
m/s
(b) Determine at what point does the ball have maximum speed?
cm (from itsoriginal position)
(c) Determine what is this maximum speed?
m/s
