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 0.0221 kg, 0.0211 kg, 0.0205 kg, and 0.0197 kg. At this very instant the x and y components of the mice's velocities are, respectively, (0.779 m/s, -0.219 m/s), (-0.801 m/s, -0.509 m/s), (0.225 m/s, 0.377 m/s), and (-0.477 m/s, 0.705 m/s). Calculate the x and y components of Bryce's mice's total momentum, px and py.

Explanation / Answer

momentum of any object having mass 'm' and velocity 'v' can be find as -

p = mv

p = 0.0221[0.779 i - 0.219 j] + 0.0211 [- 0.801 i - 0.509 j] + 0.0205 [- 0.477 i + 0.705 j] + 0.0197 [- 0-477 i + 0.705 j]

p = 0.0172 i - 0.005 j - 0.017 i - 0.0107 j - 0.0098 i + 0.0144 j - 0.0094 i + 0.0138 j

p = - 0.019 i + 0.0125 j
