A spacecraft is measured by an observer on the ground to have a length of 53 m as it flies overhead with a speed 17 times 10^8 m/s. The spacecraft then lands and its length is again measured by the observer on the ground, this time while the spacecraft is at rest relative to him. what result does he now get for the length of the spacecraft ? 44 m 53 m 59 m 62 m 64 m The work...

A spacecraft of proper length Lo = 48.0 m is moving in the +x direction at a constant Lorentz factor y = 2.20 relative to an inertial frame, the Earth frame. The spacecraft is aligned with the direction of motion. The tip of the spacecraft crosses the origin (x = 0) at tA = 0 in the Earth frame and t'A = 0 in the frame of the moving spacecraft. a.

An observer at rest on the Earth observes two spacecraft moving toward one another. Spacecraft 1 travels to the right at a velocity of 0.71 c relative to the observer. Spacecraft 2 travels to the left at a velocity of 0.71 c relative to the observer. What is the velocity of Spacecraft 1 relative to Spacecraft 2 (give your answer in terms of “c”)?

The crew of an enemy spacecraft attempts to escape from your spacecraft by moving away from you at 0.283 of the speed of light. But all is not lost! You launch a space torpedo toward the foe at 0.341 of the speed of light with respect to you. At what speed in kilometers per second does the enemy crew observe the torpedo approaching its spacecraft?

You go on a round trip in a very fast spacecraft, while your twin remains behind on Earth (at rest). (Assume that the spacecraft travels at a constant speed, except for the brief turn-around.) Your twin (on Earth) ages 25.00 years while you (on the spacecraft) age only 5.000 years. What was your speed relative to the Earth (i.e., your twin's frame of reference)? Show your work. Give your final answer as a decimal fraction of c,...

27.11 A meter stick moves past you at great speed.Its motion relative to you is parallel to its long axis. If you measure the length of the moving meter stick to be 1.90ft for example, by comparing it with a ruler that is at rest relative to you, at what speed is the meter stick moving relative to you?
