Question: A simplified model consisting of a single straight line is to be obtained for the variation of pressure inside the 0.4-in.-diameter barrel of a rifle

A simplified model consisting of a single straight line is to be obtained for the variation of pressure inside the 0.4-in.-diameter barrel of a rifle as a 0.7-oz bullet is fired. Knowing that it takes 1.6 ms for the bullet to travel the length of the barrel and that the velocity of the bullet upon exit is 2100 ft/s, determine the value e of p0.
