15. (a) From the fact that T 3 = 9.8 N, we conclude the mass of disk D is 1.0 kg. Both this and that of disk C cause the tension T 2 = 49 N, which allows us to conclude that disk C has a mass of 4.0 kg. The weights of these two disks plus that of disk B determine the tension T 1 = 58.8 N, which leads to the conclusion that

Unformatted text preview: m B = 1.0 kg. The weights of all the disks must add to the 98 N force described in the problem; therefore, disk A has mass 4.0 kg. (b) m B = 1.0 kg, as found in part (a). (c) m C = 4.0 kg, as found in part (a). (d) m D = 1.0 kg, as found in part (a)....
