Web25 mei 2024 · Solution: Chapter 9 Linear Momentum And Collisions Q.3P. · · A26.2-kg dog is running northward at 2.70 m/s, while a 5.30-kg cat is running eastward at 3.04 m/s. Their 74.0-kg owner has the same momentum as the two pets taken together. Find the direction and magnitude of the owner’s velocity. WebIn the case of a non-isolated system, the total system momentum is not conserved. Because of the inevitability of friction and air resistance in any real collision, one can conclude that no system is ever perfectly isolated. The reasoning is that there will always be a resistance force of some kind robbing the system of its momentum.
