Question

A spaceship and an asteroid are moving in the same direction away from Earth with speeds of 0.8 c and 0.45 c, respectively. What is the relative speed between the spaceship and the asteroid?

Answer 1

Answer:

0.35c

Explanation:

The relative speed between the spaceship and the asteroid can be calculated as the difference between their speeds, so it is equal to

Relative speed = 0.8c - 0.45c

relative speed = 0.35c

Therefore, the answer is

0.35c
