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? -0.156 c 0.156 c 0.8 c 0.85 c c

1. A ship is travelling away from Earth at .9 c relative to us.. A year (on the ship) into the journey some people get sick of space travel and decide to go back home. They leave in a shuttlecraft travelling at .8 c relative to the ship. A. How fast is the shuttlecraft moving relative to the Earth? B. How long was the ship travelling in Earth time? C. How far has the ship gone from the perspective of...

A spaceship at rest on the earth has a length of 120m and a mass of 16,000kg. Then the spaceship begins to move away from the earth at 3/4 speed of light. If the spaceship sends out a second ship away from the earth on what observers on the spaceship think is 1/2 speed of light, how fast do the observers on earth think the second ship is moving? If the spaceship sends out a second ship toward the earth...

Amanda pilots a space ship away from earth at a speed of 0.810c. At some moment she sends a light pulse toward earth. Exactly one year later she sends another pulse toward earth. (a) As measured in an inertial frame in which the earth is at rest, what is the difference in time between the generation of the two pulses? (b) What is the difference in time between detection of the two pulses on earth? Treat the earth as stationary,...

15 pts) A spaceship flying directly toward Earth at 0.7c launches a missle with a speed (measured m the spaceship) of 0.8c at an angle of 60 (measured from the spaceship and measured relative to the ship-Earth direction). What is the speed of the missle measured by people on Earth and what is the angle of the missle's trajectory relative to the ship-Earth direction as measured by people on Earth?
Suppose a spaceship heading directly away from the Earth at 0.65c can shoot a canister at 0.25c relative to the ship
Suppose a spaceship heading directly away from the Earth at 0.65c can shoot a canister at 0.25c relative to the ship. Take the direction of motion towards Earth as positive. Randomized Variables V1 = 0.65 c V2 = 0.25 cPart (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? Part (b) What about if it is shot directly away from the Earth (again, relative to c)?

A 1500kg space ship (including fuel) is travelling through space at 25m/s[away from Earth) To gain a little more speed, the rocket expels 400kg of fuel out the back of the ship at 40.5m/s[toward the Earth] The speed of the ejected fuel is measured relative to the space ship. 17. By the time all of the 400kg of fuel has been ejected, what will be the new speed of the spaceship?

1) As seen from Earth, what is
the speed, v, of ship B?
Express your answer using two significant
figures.
2) If ship A increases its speed by
0.10c relative to the Earth, does the relative speed
between ship A and ship B increase by 0.10c, by more than
0.10c, or by less than 0.10c? Explain.
3) Find the relative speed between ships A and B for the
situation described in part B.
