14.6 A 180-lb man and a 120-lb woman stand side by side at the same end of a 300-lb boat, ready to dive, each with a 16-ft/s velocity relative to the boat. Determine the velocity of the boat after they have both dived, if (a) the woman dives first, (b) the man dives first. : 4 kg and that the velocities 2i + 4j + 2k. Determine the 14.13 A system consists of three particles A, B, and C. We know that m = : 3 kg, mp = 2 kg, and mc = of the particles expressed in m/s are, respectively, VA = 4i + 2j + 2k, v = 4i + 3j, and vc = angular momentum Ho of the system about O. - 2.4 m B z 1.2 m Z 3 m y A VB 3 m 3.6 m VC C X
