Bryce, a mouse lover, keeps his four pet mice in a roomy cage, where they spend much of their spare time, when they're 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 0.0109 kg, 0.0175 kg, 0.0137 kg, and 0.0189 kg. At this very instant, the ?‑ and ?‑components of the mice's velocities are, respectively, (0.569 m/s,−0.521 m/s), (−0.805 m/s,−0.619 m/s), (0.321 m/s,0.455 m/s), and (−0.305 m/s,0.717 m/s).
