In an attempt to reduce the extraordinarily long travel times for voyaging to distant stars, some people have suggested traveling at close to the speed of light. Suppose you wish to visit the red giant star Betelgeuse, which is 430 ly away, and that you want your 20,000 kg rocket to move so fast that you age only 36 years during the round trip.

Check Your Understanding What happens to force and accleration as the vehicles fall together? What wil our estimate of the velocity at a collision higher or lower than the speed actually be? And finally, what would happen if the masses were not identical? Would the force on each be the same or different? How about their accelerations?
(a) What is the momentum of a 2000 kg satellite orbiting at 4.00 km/s? (b) Find the ratio of this momentum to the classical momentum. (Hint: Use the approximation that =1+(1/2)v2/c2 at low velocities.)

A spacecraft starts from being at rest at the origin and accelerates at a constant rate g, as seen from Earth, taken to be an inertial frame, until it reaches a of c/2. (a) Show that the increment of time is related to the elapsed time in Earth's frame by: d=1v2/c2dt. (b) Find an expression for the elapsed time to reach speed c/2 as seen in Earth's frame. (c) Use the relationship in (a) to obtain a similar expression for the elapsed proper time to reach c/2 as seen in the spacecraft, and determine the ratio of the time seen from Earth with that on the spacecraft to reach the final speed.
Check Your Understanding Galaxies are not single objects. How does the gravitiational force of one galaxy exerted on the “closer” stars of the other galaxy compare to those farther away? What effect would this have on the shape of the galaxies themselves?

Earth astronomers measure that two novas (sudden brightening of a star) occur simultaneously, one in the constellation Orion and the other in the constellation Lyra. Each is 2.5×103c·y from Earth, but in opposite directions. Observers in aspacecraft flying at 1000 km/h on a line from Orion to Lyra measure one nova to occurbefore the other. (a) Which nova occurs first? (b) How much time separates the twonovas? Assume Earth is an inertial reference frame.

In a science-fiction TV show, the hero spent the entire 30 min fretting about running out offuel before he could pilot his spaceship back to base. Several times in the sequence thecamera cut from his worried face to the blasting rockets, to the fuel gauge, and back to hisworried expression as the engines roared and the fuel amount keeps decreasing. Whatshould he have done and what you would say about the writers of the show?
You’re standing on an asteroid when you see your best friend rocketing by in her new spaceship. As she goes by, you notice that the front and rear of her ship coincide exactly with the 400-m-diameter of another nearby asteroid that is stationary with respect to you. However, you happen to know that your friend’s spaceship measured 500 m long in the showroom. What is your friend’s speed relative to you?
An astronaut with a mass of 75.8kg, finds herself 34.7m from her spaceship. The only way for her to return to the ship is to throw her 0.450kg wrench directly away from the ship. If she throws the wrench with a speed of 20.3m/s, how many seconds does it take her to reach the ship?
