Question 1: You wish to travel to a planet located 10 light years (ly) away. a)...
The distance to Planet (X) is 4.70 ly. How long does it take a spaceship to reach the planet, according to the pilot of the spaceship, if the speed of the ship is 0.90c?
Tau Ceti is a star that is located 11.753 ly away. There
is a planet orbiting this star with an orbital radius of 0.538 AU
(AU stands for astronimcal unit - the average distance between
Earth & the Sun). Fill in the table below by determining the
minimum diameter the objective of a telescope would need to be in
order to resolve the planet from the star at the stated
wavelengths. 1 ly = 9.461 × 1015 m & 1...
A spaceship travels from earth to a star 95 light years away at a speed of 2.2 x 10^8 m/s. how long does it take to get there (a) as measured on the earth and b) as measured by a passenger on the spaceship?
A space probe is to travel from Earth to a refueling station 5.05 ly away. At what speed must the probe travel in order for the Earth–station distance to be 2.45 ly, when measured in the reference frame of the probe? Express your answer as a multiple of c, the speed of light in a perfect vacuum. c
In an Earth reference frame, a star is 76 light-years away. How fast would you have to travel so that to you the distance would be only 39 light-years?
How fast should you fly to a planet 50 light years away if you want to get to your destination in one year of your own time?
The nearest star to Earth is Proxima Centauri, 4.3 light-years away. Part A At what constant velocity must a spacecraft travel from Earth if it is to reach the star in 4.9 years, as measured by travelers on the spacecraft? b: How long does the trip take according to Earth observers? in years
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?...
Suppose you decide to travel to a star 69 light-years away at a speed that tells you the distance is only 28 light-years. Part A How many years would it take you to make the trip? Express your answer using two significant figures.
The nearest star from our system is 4.3 ly away. How fast must a starship travel if the passengers are to age 2.0 years for the trip.
