You are going on a trip to Alpha Centauri, which is 4.3 light years away. A light year is the distance traveled by light in one year. One light year is designated as 1

cy, where c is the speed of light and y is 1 year. Hence, Alpha Centauri is a distance of 4.3 cy. You board the ship Star Ship express, which is 150 m long when it is at rest. The spaceship takes off and travels at 99% of the speed of light. You will do a flyby and collect data of the star, and then fly back to Earth. From your frame of reference, the distance is d = 4.3 cy and your velocity is v =0.99c.

1) Find the time it takes you to do the trip. This is the proper time for your frame of

reference. Hint: time = dist/velocity. Remember to consider going from Earth and coming back to Earth! t0= _________ years

2)Your friend stays back on Earth. Find the dilated time that your friend recordsfor your trip. t = _________ years

The nearest star, Proxima Centauri, is 4.22 light years from the Earth. Ignoring relative motion between the solar system and Proxima Centauri, suppose that a spacecraft accelerates from the vicinity of the Earth at 0.01g (0.01 times the acceleration due to gravity at sea level) until it reaches one-tenth the speed of light, coasts until it is time to decelerate, and then decelerates at 0.01g until it becomes to rest in the vicinity of Proxima Centauri. How long does the...

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%)

The nearest star visible on Earth beyond the Sun is Alpha Centauri. Its distance is 4.2 ly. If light travels 3.0 x 10^8 m/s, how far is this star from Earth in meters? In the next 30.0 s, the Earth will travel roughly 885 km along its orbit around the Sun. Compute its average orbital speed in m/s. If light travels 3.0 x 108 m/s, how much time does it take to travel a. one foot b. one meter c....

On his trip from the sun to Alpha Centauri, bob rests on his coffee break at an interstellar cafe, exactly midway along a line that joins the two stars. Let his break position be x=0 and his break start time =0 (again, he as at rest relative to the stars). Violent explosions occur on both stars, on the sun at position = -2.2ly and time = 0 and on Alpha Centauri at position 2.2ly and time = 0, measured in...
