Question

A light, rigid rod l = 5.55 m in length rotates
in the xy plane about a pivot through the
rod’s center. Two particles of masses m1 =
9.8 kg and m2 = 2.4 kg are connected to its
ends.

Determine the angular momentum of the
system about the origin at the instant the
speed of each particle is v = 1.83 m/s.
Answer in units of kg m2
