Problem Solving Worksheet #5 Problem An air gun with a 30-cm long barrel fires a 56-g ball straight upwards. While the ball is in the barrel, compressed air exerts a constant force of 3.2-N force upwards. The ball experiences a friction force while it is in the barrel. The result is that the ball accelerates upwards at 2.71-m/s2. Find the friction force. Notes The magnitude of the friction force is 2.5 N . This problem will require forces. Draw free-body...

A 125-g bullet is fired from a rifle having a barrel 0.580 m long. Choose the origin to be at the location where the bullet begins to move. Then the force (in newtons) exerted by the expanding gas on the bullet is 16,000 + 10,000x − 26,000x2, where x is in meters. (a) Determine the work done by the gas on the bullet as the bullet travels the length of the barrel. (Enter your answer to at least two decimal...
