A 9-mm Xian short-barrel experimental pistol is fired and the reacting, exploding gases push the bullet down the barrel of the gun. The pressure is recorded as the bullet accelerates to the exit. The sample of the pressure Distance in cm : 0 2 3 4 5 6 7 8 Pressure in gun chamber behind bullet (gage) : 23 25 24 22 17 20 6 4 What is the work done on the bullet by the expanding gases. The inside diameter is 9 mm. the answer should be 9 J. I have been trying to use integration but I am getting a really small number so I don't know what I am doing wrong.
