Bryce, a mouse lover, keeps his four pet mice in a roomy cage, where they spend much of their spare time (when they are not sleeping or eating) joyfully scampering about on the cage's floor. Bryce tracks his mice's health diligently and just now recorded their masses as 15.9g, 23.3g, 16.3g, and 18.1g. At this very instant, the and components of the mice's velocities are, respectively, (0.447m/s,0.245m/s), (0.177m/s,0.677m/s), (0.425m/s,0.499m/s), and (0.817m/s,0.755m/s).Calculate the and components of Bryce's mice's total momentum, and.
