A light, rigid rod of length l = 1.00 m joins two particles, with masses m1 = 4.

Question

A light, rigid rod of length l = 1.00 m joins two particles, with masses m1 = 4.00 kg and m2 = 3.00 kg, at its ends. The combination rotates in the xy plane about a pivot through the center of the rod (see figure below). Determine the angular momentum of the system about the origin when the speed of each particle is 3.00 m/s.

Explanation / Answer

Angular momentum= (m1+m2)vr

=(4+3)*0.5*3= 10.5 kg.m2/s
