You are an observer in a 100-m long spacecraft traveling from the earth to the moon at 0.8c. (a) What is the proper length of the spacecraft? (b) For a proper time interval of 1 sec., the relativistic time interval for the spacecraft measured from the earth reference frame would be: (c) Time dilation does not apply to all time-dependent physical and biological processes. T/F? (d) What is the relativistic length, DL measured from the reference frame of earth? (e)...
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.

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?...
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 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...
