    Help with Angular Momentum

    I dont really know if this problem fits in this section but its the best section I could find for it. Given the state vectors x=-6574330.3, y=-418132.2, z=1392264.8, Vx=-889, Vy=7490.39 and Vz=-1941.32 of a spacecraft that is 22942.2kg, can you calculate the angular momentum of the spacecraft? I have already attemped this problem and got an angular momentum magniude of 1.20315389e+15 m2kg/s but i dont know if it is right. By the way the position vectors of the spacecraft are in meters and the velocity vectors are in m/s. Also, its the angular momentum that is required to finish calculating the eccentricity and not the angular momentum vector components right?

    I get |\vec{L}| = 1.68 \times 10^{15}
