Question

The crew of an enemy spacecraft attempts to escape from your spacecraft by moving away from you at 0.263 of the speed of light. But all is not lost! You launch a space torpedo toward the foe at 0.341 of the speed of light with respect to you. At what speed in kilometers per second does the enemy crew observe the torpedo approaching its spacecraft? speed: km/s

Step 1

Given: Speed of enemy spacecraft (v) = 0.263c Speed of torpedo launched (u) = 0.341c Calculate the relative speed (u') using the formula: u' = (u - v) / (1 - uv/c^2) u' = (0.341 - 0.263) / (1 - 0.341 * 0.263) u' = 0.078 / (1 - 0.089983) u' = 0.078 / 0.910017 u' ≈ Show more…
