Question:

For the satellite system of Prob. 14.9, assuming that the velocity of the base satellite is zero, determine

(a) The position vector r of the mass center G of the system,

(b) The linear momentum mv̅ of the system,

(c) The angular momentum HG of the system about G. Also, verify that the answers to this problem and to Prob. 14.9 satisfy the equation given in Prob. 14.27.

PROBLEM 14.9

A 20-kg base satellite deploys three subsatellites, each which has its own thrust capabilities, to perform research on tether propulsion. The weights of subsatellite A, B, and C are 4 kg, 6 kg, and 8 kg, respectively, and their velocities expressed in m/s are given by v_A = 4i - 2j + 2k, v_B = i + 4j, v_C = 2i + 2j + 4k. At the instant shown, what is the angular momentum H_o of the system about the base satellite?
