A 420-kg space vehicle traveling with a velocity v0 = ( 390 m/s)i passes through the origin O at t = 0. Explosive charges then separate the vehicle into three parts, A, B, and C, with mass, respectively, 210 kg, 100 kg, and 110 kg. Knowing that at t = 4 s. Determine the corresponding positions at part C?
