Question

Spaceship #1 is moving at a speed of  to the right,and Spaceship #2 is moving to the left also at  ,both speeds measured with respect to the Earth.What is the speed of #1 as measured by an observer on #2?

Quizplus · Accepted Answer

To calculate the velocity of #1 as measured by an observer on #2, we need to use the relative velocity formula: V₁₂ = V₁ₑ - V₂ₑ
where,
V₁₂ = velocity of #1 as measured by an observer on #2
V₁ₑ = velocity of #1 with respect to Earth
V₂ₑ = velocity of #2 with respect to Earth

Plugging in the given values, we get:
V₁₂ = 11eaa64f_8fa2_a6f8_a696_cd5d3c113070_TB5258_11 - ( -11eaa64f_8fa2_ce09_a696_5ba736d337a0_TB5258_11 )
     = 22eaa64f_8fa2_f51b_a696_bd192e634963_TB5258_11
     = 11eaa64f_8fa2_f51b_a696_bd192e634963/2_TB5258_11

Therefore, the answer is B: 11eaa64f_8fa2_f51b_a696_bd192e634963_TB5258_11.
