A spaceship of proper length Lp = 400 m moves past a transmitting station at a speed of 0.61c. (The transmitting station broadcasts signals at the speed of light) A clock is attached to the nose of the spaceship and a second clock is attached to the transmitting station. The instant that the nose of the spaceship passes the transmitter, clocks at the transmitter and in the nose of the spaceship are set to zero. The instant that the tail...

A spaceship of proper length Lp = 350 m moves past a transmitting station at a speed of 0.89c. (The transmitting station broadcasts signals that travel at the speed of light.) A clock is attached to the nose of the spaceship and a second clock is attached to the transmitting station. The instant that the nose of the spaceship passes the transmitter, the clock attached to the transmitter and the clock attached to the nose of the spaceship are set...

A spaceship travels through the dock of a space station without slowing down. The speed of the spaceship relative to the station is v = 4c/5, where c is the speed of light. Consider frames of reference in the standard configuration with v and all distances aligned along the x-axis. Primed variables refer to events in the station frame and unprimed to events in the spaceship frame. The dock has a length of L′ = 200 m in the station...

1. The control panel on a spaceship contains a light that blinks every 3.01 s as observed by an astronaut in the ship. If the spaceship is moving past Earth with a speed of 0.743c, determine the proper time interval between blinks and the time interval between blinks as observed by a person on Earth. A. the proper time interval (in s) between blinks ___________ s B. the time interval (in s) between blinks as observed by a person on...

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...

Observer A on Earth sees spaceship B moving at speed v = 0.600c0 away from Earth and spaceship C moving at the same speed in the opposite direction. Observer A determines that both ships simultaneously sent out a radio signal at 12:00:00 noon and another signal at 12:05:00 p.m., making the time interval A measures between the emission of the signals from each ship ?tA = 5.00 min . Let ?tBB denote the time interval measured on ship B between...

A spaceship is 1600 m long when it is at rest. When it is traveling at a certain constant speed its length is measured by external observers and it is found to be 505 m. What is the speed of the spaceship in terms of the speed of light? 2.84*10^8 Hints: Objects moving at relativistic speeds shrink in the direction of motion. This is the so called Lorentz contraction. What is the relationship between the speed of the spaceship, its...

4) A spaceship leaves earth (event A), travels to Alpha Centauri, and then returns to earth exactly 15.0 y later (event B) with respect to clocks on the earth. Alpha Centauri is 4.3 ly from earth. The spaceship's acceleration time is so short that it spends virtually all of its time traveling at a constant speed. a) If the spaceship travels straight towards Alpha Centauri and back again, what is the time between events A and B as measured by...
