The mechanical system moves in such a way that the projections of the acceleration of its center of mass C on the coordinate axis are equal to aCx = 1 m / s2, aCy = 2 m / s2, aCz = 4 m / s2. Determine the modulus of the principal vector of external forces acting on the system, if the mass of the system is m = 40 kg. (Answer 183)
