Question
Sapling Learning nacmillan learning Bryce, a mouse lover, keeps his four pet mice in a roomy cage, where they spend much of their soare 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 0.0209 kg, 0.0195 kg, 0.0205 kg, and 0.0197 kg. At this very instant the x and y components of the mice's velocities are, respectivel (0 365 m s -0.713 s 1-0 237 s,-0107 s), 0.987 ms, o 749 s and (0973 m s 0493 m/s).

Explanation / Answer
px = mi*vix
px = (0.0209*0.365 - 0.0195*0.237 + 0.0205*0.987 - 0.0197*0.973)kg·m/s
px = 0.0040724kg·m/s
py = mi*viy
py = (-0.0209*0.713 - 0.0195*0.107 + 0.0205*0.749 + 0.0197*0.493)kg·m/s
py = 0.0080784 kg·m/s
