A light rigid rod of length l= 1.00 m rotates about an axis
perpendicular to its length and through its center, as shown
in Figure P8.51. Two particles of masses m1 = 4.00 kg and
m2 = 3.00 kg are connected to the ends of the rod. What is the
angular momentum of the system if the speed of each particle
is 5.00 m/s? (Neglect the rod’s mass.)
