51. We apply Newton’s second law first to the three blocks as a single system and then to the individual blocks. The + x direction is to the right in Fig. 5-49. (a) With m sys = m 1 + m 2 + m 3 = 67.0 kg, we apply Eq. 5-2 to the x motion of the system – in which case, there is only one force G G TT 33 =+ # i . Therefore, 3s y s 65.0 N (67.0kg) Tm a a = ¡ = which yields a = 0.970 m/s 2 for the system (and for each of the blocks individually).
