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 24.9 g, 11.3 g, 19.5 a, and 23.7 g. At this very instant the x and y components of the mice's velocities are, respectively. ( 0.809 m / s. - 0.451 m / s ) . ( - 0.413 m / s, - 0.395 m / s ) . ( 0.523 m / s. 0.991 m / s ) , and ( - 0.473 m / s, 0.497 m / s ) . Calculate the x and y components of Bryce's mice's total momentum, px, and Py.

Explanation / Answer

Momentum in x direction = m1vx1 +m2vx2 + m3vx3 + m4vx4 = 24.9*0.809 + 11.3*(-0.413) + 19.5*(0.523) + 23.7*(-0.473) gm.m/s = 14.4656 gm.m/s = 0.0144656 kg.m/s Momentum in y direction = m1vy1 +m2vy2 + m3vy3 + m4vy4 = 15.41 gm.m/s = 0.01541 kg.m/s
