A spaceship moves at a speed of 0.85 c away from the Earth. It shoots a torpedo toward the Earth at a speed of 0.8 c relative to the ship. The defenders of Earth respond by blasting high energy x-rays at the torpedo in an attempt to destroy it. What is the velocity of the x-rays relative to the Earth?

suppose a spaceship heading directly away from the Earth at 0.75c can shoot a canister at 0.65c relative to the ship. Take the direction of motion towards Earth as positive. v1= 0.75 c v2= 0.65 c a) If the canister is shot directly at Earth, what is the ratio of its velocity, as measured on Earth, to the speed of light?

The spaceship Enterprise 1 is moving directly away from earth at a velocity that an earth-based observer measures to be +0.69c. A sister ship, Enterprise 2, is ahead of Enterprise 1 and is also moving directly away from earth along the same line. The veolcity of Enterprise 2 relative to Enterprise 1 is +0.45c. What is the velocity of Enterprise 2, (in terms of c) as measured by the earth-based observer?

Observer A on Earth sees spaceship B moving at speed v = 0.600c0 away from Earth and spaceship C moving at the same speed in the opposite direction. Observer A determines that both ships simultaneously sent out a radio signal at 12:00:00 noon and another signal at 12:05:00 p.m., making the time interval A measures between the emission of the signals from each ship ?tA = 5.00 min . Let ?tBB denote the time interval measured on ship B between...
