A 0.4-kg particle is located at the position r₁ = 2i + 3j + k m and has the velocity v₁ = i + j +2k m/s at time t = 0. If the particle is acted upon by a single force which has the moment M_O = (4 + 2t)i + about the origin O of the coordinate system in use, determine the angular momentum about O of the particle when t = 4 s.
