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 0.0235 kg, 0.0205 kg, 0.0237 kg, and 0.0207 kg. At this very instant the x and y components of the mice's velocities are, respectively, (0.425 m/s, -0.265 m/s), (-0.835 m/s, -0.563 m/s), (0.129 m/s, 0.329 m/s), and (-0.317 m/s, 0.687 m/s). Calculate the x and y components of Bryce's mice's total momentum, px and py.

Explanation / Answer

when mass = 0.0235kg velocity isVx=0.425m/s , Vy = -0.265m/s

Px = mVx = 0.0235*0.425 =0.0099875 Kg-m/s

Py = mVy = 0.0235*(-0.265) =-0.006227 Kg-m/s

When mass = 0.0205kg velocity Vx = -0.835kg Vy = -0.563m/s

Px = mVx = 0.0205*[-0.835] = -0.0171Kg-m/s

Py = mVy = 0.0205*[-0.563] =-0.01154Kg-m/s

when mass = 0.0237kg Vx = -0.129m/s Vy = -0.329m/s

Px = 0.0237*[-0. 129] = -0.003057Kg-m/s

Py = 0.0237*[-0.329]=-0.0077937Kg-m/s

when mass = 0.0207kg Vx = -0.317m/s Vy = 0.687m/s

Px = 0.0207*[-0.317] = -0.006561Kg-m/s

Py = 0.0207*[0.687] = 0.01422Kg-m/s
