PHY-102: Energy and Circular Motion Exercises Complete the following exercises. 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. By the theory of momentum, change in momentum of an object equals the impulse applied to it meaning that the long barrel of the rifle covers a huge amount of motion of the bullet since the bullet receives more impulse from the expanding gases with...

Physics 121 Final Exam Review BYU IS: Exam Review Questions & Answers/ how many standard balloons can fit into a minivan? about 200 A standard helium balloon is of the order of a foot across. The inside of a minivan is about 5 feet across by 4 feet high by 8 feet long. That is a volume of about 200 cubic feet. Probably only about 2/3 of that can be used for balloons, so 200 is probably too high, but it is closer than any of the other answers. carrying bucket at constant speed, what wor...
