Answer to Problem 47P

  0.92c

Explanation of Solution

Given:

Speed of first spaceship is 0.60c

Speed of second spaceship is +0.70c

Formula used:

It is known that

  u=(v+u')1+vu'c2

Where,

  m is relativistic mass

  v is velocity (with the respect to the earth)

  u' is a speed (Or speed respect to the first speed)

  c is speed of light, 3.00×108m/s

If u' is in the opposite direction from v then u' must have a minus sign in the above mentioned expression.

Calculation:

From the first pod’s point of view, the spaceship and the second pod are moving in the same direction.

So, the speed of the second pod relative to the first is

  u=(0.60c+0.70c)1+(0.60)(0.70)=0.92c

Conclusion: The required value is 0.92c .
