Determine at what point does the ball have maximum speed

Reference no: EM13669413

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)

m/s
