Aspaceship in distress sends out two escape pods in opposite directions. one travels at a speed v1 = + 0.70 c in one direction, and the other travels at a speed v2 = − 0.76 c in the other direction, as observed from the spaceship. part a what speed does the first escape pod measure for the second escape pod? express your answer using two significant figures.

To develop this problem it is necessary to apply the related concepts at relative speed.

When an observer perceives the relative speed of a second observer, the function is described,

Where,

= The velocity of the first escape pod

= The velocity of the second escape pod

c = Speed of light

v' = Speed of the first escape pod relative to the second escape pod.

Our values are given as,

= 0.7c

= -0.76c

Replacing we have,

Therefore the speed of the first escape pod measure for the second escape pod is

i. like it i'm gonna edit it tomorrow
