As you pilot your space utility vehicle at a constant speed toward the moon, a race pilot flies past you in her spaceracer at a constant speed of 0.830c, relative to you. At the instant the space-racer passes you, both of you timers at zero. At the instant when you measure that the spaceracer has traveled 1.13 x 10°m past you, what de the race pilot read on her timer?

If a spaceship, approaching the Earth at 0.300c, sends a message capsule toward the Earth at 0.410c relative to the Earth, what is the speed of the capsule relative to the ship? Express your answer in terms of the speed of light, c.

Two rockets fly away from the Earth in opposite directions. Each rocket is moving at a speed of v = 0.83 c as seen from the Earth. a. How fast is rocket "B" moving as seen by the astronaut in rocket "A"? Express your answer as a decimal fraction of the speed of light. b. If the astronaut on rocket "A" measures a time interval of 60 minutes, how much time would they say goes by for the astronaut on rocket "B"? minutes c. Rocket "A" travels out from Earth at a speed of v = 0.83 c for a period of one year as measured on Earth, turns around, and then travels back to the Earth at the same speed for another Earth year. How much did the astronaut on the rocket age? years

The inertial reference frames, S and S', both share the same origin at t = t'= 0. The 5' trame is moving at a speed 0.700c in the positive direction, as seen by frame S. An event happens at (1', x', y', z') = (300s, 2.50×10m,1.50×10"m, 2.90x10"m), as observed in the S' frame. What are the spacetime coordinates in the S frame?

An astronaut travels to the next star at 0.95c and back. He notices that hishike took him 11 years. When he returns, what will be the period of timethat will have passed on Earth during his absence?

A UFO Strikes across the sky at a speed of 0.90c relative to the earth. Aperson determines the length of the UFO to be 230 m along the directionof its motion. What length does the person measure for the UFO when itlands?

A person on earth notices a rocket approaching from the right at a speed of 0.71c and another rocket approaching from the left at 0.66c. What is the relative speed between the two rockets, as measured by a passenger on one of them? Number VLE Earth's rest frame Units VRE ◄►

An observer in reference frame S' observes that a lightning bolt strikes the origin, and 1.0×10−4 s later a second lightning bolt strikes the same location. What is the time separation delta t between the two lightning bolts determined by a second observer in reference frame S moving at a speed of 0.90c along the collinear x-x'-axis? delta t = ? s

A spacecraft has a speed of 0.4c relative to Earth. As measured on Earth, the elapsed time between two events that happen at the same location on Earth is 4 h. Determine what the elapsed time between those two events would be from the spacecraft's frame.
