A 900-lb space vehicle traveling with a velocity vo = (1540 ft/s)k passes through the origin O. Explosive charges then separate the vehicle into three parts, A, B, and C, with masses of 150 lb, 300 lb, and 450 lb, respectively. Knowing that shortly thereafter the positions of the three parts are, respectively, A(250, 250, 2250), B (600, 1300, 3200), and C(-475,- 950, 1900), where the coordinates are expressed in ft, that the velocity of Bis vB= (500 ft/s)i + (1100 ft/s)j + (2100 ft/s)k, and that the x component of the velocity of Cis - 400 ft/s, determine the velocity of part A. The velocity of part Ais va=( 200 ft/s)i + 172 ft/s)j + (1560 ft/s)k.
