Question

Bryce, a mouse lover, keeps his four pet mice in a roomy cage, where they spend much of their spare timewhen they're not sleeping or eatingjoyfully scampering about on the cage's floor. Bryce tracks his mice's health diligently and just now recorded their masses as 0.0221 kg, 0.0251 kg, 0.0143 kg, and 0.0159 kg. At this very instant the x and y components of the mice's velocities are, respectively, (0.863 m/s, -0.625 m/s), (-0.537 m/s, -0.419 m/s), (0.657 m/s, 0.689 m/s), and (-0.129 m/s, 0.655 m/s). Calculate the x and y components of Bryce's mice's total momentum, px and py.

Explanation / Answer

Hey
just multiply each mouse's mass by its velocity components
then
add them up to get and x,y total
