Question

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 diagrams for the ball. .Be sure to write your answer in vector notation
