Serway & Jewett β Energy of a System: Problem 18.
A 100-g bullet is fired from a rifle having a barrel 0.600 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 \(15\,000 + 10\,000x - 25\,000x^2\), 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. (b) What If? If the barrel is 1.00 m long, how much work is done, and (c) how does this value compare with the work calculated in part (a)?
π Solution Approach
Given: 0.600 m, 1.00 m
Find: (a) Determine the work done by the gas on the bullet as the bull; (b) What If? If the barrel is 1; (c) how does this value compare with the work calculated in part
