Question

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 0.0125 kg, 0.0245 kg, 0.0135 kg, and 0.0131 kg. At this very instant the x and y components of the mice's velocities are, respectively, (0.499 m/s, -0.271 m/s), (-0.181 m/s, -0.461 m/s), (0.711 m/s, 0.135 m/s), and (-0.453 m/s, 0.273 m/s). Calculate the xand y components of Bryce's mice's total momentum, px and py.

Explanation / Answer

X-component of total momentum = (0.0125*0.499) + (0.0245*-0.181) + (0.0135*0.711) + (0.0131*-0.453)

= 0.0054672 Kg m/s

Y-component of total momentum = (0.0125*-0.271) + (0.0245*-0.461) + (0.0135*0.135) + (0.0131*0.273)

= -0.0092832 Kg m/s
