A rocket ship leave earth at a speed of 0.6clative to earth, where represents speed of light in vacuum. When the clock on the rocket says 1 hours has elapsed, the rocket sends a light signal back to earth
According to a clock on earth, when was the light signal sent?
According to a clock on earth, how long after the rocket left earth did the light signal arrive (explain clearly)

Y a rocket of rest length 90 meters es traveling at speed yc directly away from the earth! The rocket encounters an asteroid of length? 80 nheters also traveling directly away from the earth but atspred zc. a) According to the captain of the rocket, what is the velocity of the rocket relative to the asteroid? (6) at the front of the rocket, the captain of the rocket becomes aware of the asteroid and activates a warning signal. It takes...
Xena is going home from an interplanetary travel. Her ship is directed to Earth and is traveling at speed v. When she is at a distance L from Earth (in her reference frame) she sends a signal to her husband Yan to get the dinner ready. In her reference frame the dinner takes a time tD to cook. a) How far is she from Earth when she sends the signal in Yan’s reference frame? b) How long will it take...
Having trouble with this. Dont know where to start.
A spaceship travels at 0.540 Co away from Earth. When the ship is 2.57x1011 m away in the Earth reference frame, the ship clock is set to t = 0 and a message (light signal) is sent to its ground crew on Earth. When this message is received the ground crew immediately sends a reply (light signal) to the ship. The ground crew adjust their clocks to specify t = 0...
An astronaut travels away from the Earth at a speed of 0.74c and sends a light signal back to the Earth every 9.0 s as measured by his clock. An observer on the Earth finds that the arrival time between consecutive signals is Δt. Find Δt. (Answer should be in seconds)
A ship is flying away from Earth at 0.9c (where c is the speed of light). A missile is fired that moves toward the Earth at a speed of 0.5c relative to the ship. How fast does the missile move relative to the Earth
A and B leave from a common point (with both of their clocks reading zero) and travel in opposite directions with relative speed v. When B’s clock reads T, he (B) sends out a light signal. When A receives the signal, what time does his (A’s) clock read? Answer this question doing the calculation entirely in a) A’s frame and then b) on B’s frame. I know the answer for both a) and b) is T/(y(1-c/v)), but I am not...
Abby leaves Earth on a spaceship traveling at speed v while Bill stays on earth. After time ∆t′ has passed according to Abby’s watch, she sends Bill a signal. (a) Draw a spacetime diagram labelling Abby, Bill, the signal, and each event. (b) How much time passes before Abby sends the signal, according to Bill’s reference frame? (Answer in terms of v, c, and ∆t′) (c) When does Bill receive the signal, according to his wristwatch? (Answer in terms of...
a spaceship of proper length 50 m is moving away from the earth at a speed of .8c . according to the observes in the ship , their journey takes 6.0 hours . according to observers on earth , what is the length of the ship and how long does the journey take ?
You travel in ship
2) You travel in your ship White Star One at a constant speed of v 0.96*c to the nearby star Proxima Centauri, located 4.2 light years away from Earth. a. From your point of view in the ship, how far is the star from the Earth? b. If your mass is 68 kg, what is your kinetic energy while moving with the ship? c. How long does the journey take, according to clocks on your ship?...
piloting a state-of-the-art spaceship to α Centauri, which is a star about 4 lightyears away as measured from Earth. Your ship cruises at a speed of 0.6c. For this problem, you can assume that Earth and a Centauri are at rest with respect to each other. At your journey's midpoint, you decide to send a souvenir package to your folks back home. You launcha probe back to Earth at a speed of v 0.8c from your perspective. a. How long...
