4/8 The angular momentum of a system of six particles about a fixed point O at time t = 4 s is H, = 3.65i +4.27j – 5.36k kg-m³/s. At

time t = 4.1 s, the angular momentum is H41 Determine the average value of the resultant moment about point O of all forces acting on all particles during the 0.1-s interval.
