A spaceship leaves Earth traveling at 0.75 c. A second spaceship leaves the first at a speed of 0.87 c with respect to the first.
Part A
Calculate the speed of the second ship with respect to Earth if it is fired in the same direction the first spaceship is already moving. Take the positive direction in the direction of the first spaceship.
Part B
Calculate the speed of the second ship with respect to Earth if it is fired directly backward toward Earth.

A spaceship leaves Earth traveling 0.67c. A second spaceship leaves the first at a speed of 0.94c with respect to the first. Calculate the speed of the second ship with respect to Earth if it is fired as follows. a) In the same direction the first spaceship is already moving The correct answer for part a is 0.9878c but I can't seem to find the correct answer for part b. b) Directly backward toward Earth
A spaceship leaves Earth traveling 0.5c. A second spaceship leaves the first at a speed of 0.8c, directly backward toward Earth. Calculate the speed of the second ship with respect to the Earth.
A spaceship travels with a speed of 0.3 c as it passes by the Earth on its way to a distant star, as shown in the diagram below. The pilot of the spaceship measures the length of the moving ship as 40 m. 0.3 c Earth Determine its length as measured by a person on Earth. (part 2 of 3) The pilot of the spaceship observes that the spaceship travels for 4 years. Determine how much time has passed according...
Duck Dodgers hops in his spaceship and leaves the Earth at a constant velocity of 0.6c in an attempt to reach the newly discovered Planet X before aliens from Mars. a) Mission control on Earth sends an encoded message (a flashing beacon) to Duck Dodgers warning him about the progress of the Martian ship. The light pulses travel at a speed c relative to observers on the Earth. How fast are the pulses traveling relative to Duck Dodgers? b) Duck...
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? (units for answer in mu/c=...) b) What about if it is shot directly away from the Earth (again, relative...
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...
Imagine a spaceship traveling at a constant speed through outer space. The length of the ship, as measured by a traveler aboard the ship, is 30.8 m. An observer on Earth, however, sees the ship as contracted by 19.7 cm along the direction of motion. What is the speed of the spaceship with respect to the Earth? (Express the speed as a fraction of c, the speed of light in a vacuum.) v c =
4) A spaceship leaves earth (event A), travels to Alpha Centauri, and then returns to earth exactly 15.0 y later (event B) with respect to clocks on the earth. Alpha Centauri is 4.3 ly from earth. The spaceship's acceleration time is so short that it spends virtually all of its time traveling at a constant speed. a) If the spaceship travels straight towards Alpha Centauri and back again, what is the time between events A and B as measured by...
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)?
