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, 0.0121 kg, 0.0183 kg, and 0.0189 kg. At this very instant the x and y components of the mice\'s velocities are, respectively, (0.615 m/s, -0.693 m/s), (-0.983 m/s, -0.375 m/s), (0.525 m/s, 0.705 m/s), and (-0.165 m/s, 0.755 m/s). Calculate the x and y components of Bryce\'s mice\'s total momentum, px and py.

Answer 1

Given

m₁ =0.0125kg ,m₂ =0.0121kg , m₃ =0.0183kg and m₄ =0.0189kg

v₁ =(0.615 m/s, -0.693 m/s)

v₂ = (-0.983 m/s, -0.375 m/s)

v₃ = (0.525 m/s, 0.705 m/s)

v₄ = (-0.165 m/s, 0.755 m/s)
