B. You are requested to participate in a court case as an expert witness. As illustrated in Fig. 6, a spacecraft is known to have unfortunately exploded into three pieces, A, B, and C. ma - 1000 kg, ma = 500 kg, and mc = 500 kg. Telemetry data showed that the positions of the satellitc with respect to a know wn reference ce position O at a particular tim ime were Rwo = (400 i - 1000 ) m, Ro = 1000 j m, and Reo = (800 i + 1000 j) m. The respective velocities were V, = -500j m/s, VB = (-4001 + 500) m/s, and Vc = (400i + 500) m/s. The engineer of the spacecraft company claims that a single explosion caused the described configuration, whereas the lawyer representing the insurance ce company contends that at least two separate explosions were responsible. Who is correct? (You have to describe detailed reasons and calculation results to support your answer. O point will be given if no explanation is provided.)
