Three crates with various contents are being pulled by a 3695-n force across a horizontal, frictionless roller-conveyor system. the group of boxes is accelerating on the conveyor at 1.408 m/s2 to the right. between each adjacent pair of boxes is a force meter that measures the magnitude of the tension in the connecting rope. assume that the ropes and force meters are massless. m1> > scale reads 1401 n> > m2> > scale reads 2365 n> > > 3695 n (f net) i know the total mass of the three boxes is fnet=ma which equals 2624. but how do i find the individual masses of m1, m2, m3?
