Physics

A child's play rifle uses a spring to fire a 5.21-g soft plasticball. The spring is compressed by 4.99 cm and has a spring constantof 7.94 N/m. When the rifle is fired, the ball moves 14.1 cmthrough the horizontal barrel of the rifle, and the barrel exerts aconstant friction force of 0.032 7 N on the ball.

(a) With what speed does the ball leave the barrel of therifle?

Make certain you have correctly converted all of the centimeter andgram quantities to MKS units. m/s

(b) At what point does the ball have maximum speed?

The maximum speed does not occur at the equilibrium point of thespring, because the friction force is also present throughout themotion. cm (from its original position)

(c) What is this maximum speed?
