Question

A spaceship moves at a speed of 0.85 c away from theEarth. It shoots a star wars torpedo toward the Earth at aspeed of 0.80 c relative to the ship. What is the velocity ofthe torpedo relative to the Earth? (The direction in which the spaceship moves is the positivedirection) A spaceship moves at a speed of 0.85 c away from theEarth.

(The direction in which the spaceship moves is the positivedirection)

Explanation / Answer

earths speed = X in some direction.

spaceship speed = 0.85c + X in the direction of earths movement.

torpedo speed = 0.85c + X - 0.8c in the direction of earths movement.

torpedo speed with respect to earth = 0.5c in the direction of earth's movement.
