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 0.0153 kg, 0.0147 kg, 0.0165 kg, and 0.0113 kg. At this very instant the x and y components of the mice's velocities are, respectively, (0.813 m/s, -0.361 m/s), (-0.555 m/s, -0.199 m/s), (0.751 m/s, 0.677 m/s), and (-0.815 m/s, 0.169 m/s). Calculate the x and y components of Bryce's mice's total momentum, px and py.

Explanation / Answer

Mass of first mice= 0.0153 kg, velocity=0.813x-0.361y

mass of second mice= 0.0147 kg, velocity=-0.555x-0.199y

MAss of third mice= 0.0113 kg, velocity=0.751x+0.677y

momentum of 1st mouse= 0.0124x-0.0055y

momentum of 2nd mouse= -0.00815x-0.0029y

momentum of 3rd mouse=0.0084x+ 0.0076y

Total momentu of Bryce's mice=0.01265x-0.0008y

Px=0.01265(kg. m/s)

Py=-0.0008(kg. m/s)
