Momentum impulse theorem - Study guides, Class notes & Summaries

Phy-102 Energy and Circular Exercises Question 1. A rifle with a longer barrel can fire bullets with a larger velocity than a rifle with a shorter barrel. a. Explain this using the impulse-momentum theorem. b. Explain this using the work-energy theorem A. According to the impulse momentum the impulse must be dependent on the applied force. This is Impulse=applied force*time). The longer barrel allows the gases to expand more, which will push the bullet for longer. Which will have increa...
