5. An astronaut is traveling from the Earth to the planet Neptune. At a speed of 0.73 c, the trip takes 2.75 hours in the astronaut’s frame of reference.

a) How much time does it take in the Earth’s frame of reference?

b) What is the distance from the Earth to Neptune in the Earth’s frame of reference?

c) While traveling in the rocket the astronaut measures the length of the ship to be 826 m and the radius to be 85.0 m. What is the volume of the ship as measured in Earth’s frame of reference while the ship is moving?

The star Arcturus is 36 light-yr from the earth (1 light-yr=9.463*10^15 m). At what speed must a space ship travel relative to the earth so that this distance is shortened to 1.0 light-yr as measured in the rest frame of the ship? What time, as measured by a clock carried in the ship, is needed for this trip from earth to start? (5%)

Sam is on a spaceship that travels from Earth to Proxima Centauri at 70% the speed of light, or 0.7c, relative to Earth. Erma is an observer on Earth. From Sam's perspective, 1.35 x 108 seconds passed between when the Earth was near him and when Proxima Centauri is near him First we consider velocity and time: How fast in m/s is Sam moving as measured in the rest frame of the rocket? How fast in m/s is Erma moving...

The Helios spacecraft traveling at a speed of 0.60 c relative to the Earth-Sun system, detects the explosion of a very powerful solar flare at it passes by the Sun on its way to Earth. Sometime later on Earth, the constellation of satellites used to track GPS positions fails. Using the data from the Helios spacecraft as it passes by Earth, scientists calculate that the solar flare happened 7.0 min before the failure of the satellites, according to clocks on...
