Spaceships A, B, and C have the same proper length I, and according to an observer on Earth, are moving with same relativistic speed v in the +z, -, and -v direction, respectively. Find the length of each spaceship as measured by an observer in the Spaceship A. Spaceships A, B, and C have the same proper length I, and according to an observer on Earth, are moving with same relativistic speed v in the +z, -, and -v direction,...
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. What is the speed parameter of the spaceship B?...
general relativity A spaceship of proper length Lp = 350 m moves past a transmitting station at a speed of 0.77c. (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...
The length of a moving spaceship is 30.4 m according to an astronaut on the spaceship. If the spaceship is contracted by 15.8 cm according to an Earth observer, what is the speed of the spaceship? (in c)
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...
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 of proper length 50 m is moving away from the earth at a speed of .8c . according to the observes in the ship , their journey takes 6.0 hours . according to observers on earth , what is the length of the ship and how long does the journey take ?
A spaceship at rest on the earth has a length of 120m and a mass of 16,000kg. Then the spaceship begins to move away from the earth at 3/4 speed of light. If the spaceship sends out a second ship away from the earth on what observers on the spaceship think is 1/2 speed of light, how fast do the observers on earth think the second ship is moving? If the spaceship sends out a second ship toward the earth...
