Problem 51
Q

A spaceship in distress sends out two escape pods in opposite directions. One travels at a speed v1=+0.70cv_1 = +0.70c in one direction, and the other v2=−0.80cv_2 = -0.80c travels at a speed in the other direction, as observed from the spaceship. What speed does the first escape pod measure for the second escape pod?

A
−0.962c-0.962c
