Practice Problem 27.3 SOLUTION A spaceship flies past earth with a speed of 0.980c (about 2.97 x 10 m/s) relative to earth. A crew member on the spaceship measures its length, obtaining the value 400 m. What is the length measured by observers on earth? SET UP The length of the spaceship in the frame in which it is at rest (400 m) is a proper length in this frame, corresponding to lo in We want to find the length...

1a) A rocket ship in deep space accelerates from rest at a constant rate of 9.6 m/s2, which is close to the acceleration of gravity on earth and would give the sensation of near-normal gravity during the voyage.How long will it take the ship to reach 0.103c (c = speed of light, 3.0 x 108 m/s)? Your answer should be in s, but enter only the numerical part in the box. You can use exponential notation, if desired. For example,...

ANSWER 3A, B, AND C!
3. The star system that is closest to the earth is Alpha Centauri. It is 4.37 light years away in Earth's reference frame. The fastest spacecraft humans have ever launched is New Horizons, which sent us sweet pictures of Pluto in 2015. It attained a speed of 45 km/s relative to the sun. That's fast, but even at this rate, interstellar travel is not practical. a) Traveling at 45 km/s, how long, in years, would...
