Quizplus · Accepted Answer

To find the magnitude of the velocity of spacecraft A as observed from spacecraft B, we need to find the relative velocity between spacecraft A and spacecraft B. This can be found by subtracting the velocity of spacecraft B from the velocity of spacecraft A.

11eaa64f_8fa1_475c_a696_cb4e5e3d1029_TB5258_11 - 11eaa64f_8fa1_6e6d_a696_61afb8b22a41_TB5258_11 = 11eaa64f_8fa1_957f_a696_a1967db4d08b_TB5258_11

The magnitude of this velocity is 11eaa64f_8fa1_957f_a696_a1967db4d08b_TB5258_11, which corresponds to choice B.
