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 is flying with a speed of 0.250c relative to the Earth. The spaceship fires a missile with a speed of 0.500c relative to it. What is the speed of the missile as measured by an observer on Earth?
A spaceship is flying with a speed of 0.250c relative to the Earth. The spaceship fires a missile with a speed of 0.500c relative to it. What is the speed of the missile as measured by an observer on Earth? a) 0.667c b) 0.650c c) 0.866c d) 0.776c
Please show every step Two spaceships approach Earth with equal speeds, as measured by an observer on Earth, but from opposite directions. A meterstick on one space- ship is measured to be 60 cm long by an occupant of the other spaceship. What is the speed of each spaceship, as measured by the observer on Earth? (A) 0.4c (B) 0.5c (C) 0.6c (D) 0.7c (E) 0.8c
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...
7.A spaceship is flying with a speed of 0.300c relative to the Earth. The spaceship fires a missile with a speed of 0.600c relative to it. The speed of the missile as measured by an observer on Earth is 0.763c. If we assign the spaceship as reference frame S, the missile as reference frame S', and the Earth as the "event", which of the following is correct? a) u = 0.600c; vx = 0.300c; v'x = 0.763c b) u =...
Suppose a spaceship heading directly away from the Earth at 0.75c can shoot a canister at 0.35c relative to the ship. Take the direction of motion towards Earth as positive. Randomized Variables V1 = 0.75c V2 = 0.35cPart (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)?
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 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
If a spaceship is approaching the earth at 0.38c and a message capsule is sent toward it at 0.38c relative to the earth, what is the speed of the capsule relative to the ship?
