- The total linear momentum of a system of five particles at time t =2.2 s + is given g (23) = 3.41 2.6j +4.6k kg m/s At time t

= 2.4 s, the linear momentum has changed to G(2.4) = 3.7i – 2.2j + 4.9k kg-m/s. Calculate the magnitude F of the time average of the resultant of the external forces acting on the system during the interval
