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...

Problem 2 please
Relativity: Ar-ar- Relativistic addition of velocities: -- Problem 1. A child riding a train throws a ball with speed 2/5 of the speed of light in the +x direction, in the train's reference frame. The train itself is moving at a constant speed of 2/5 in the +x direction with respect to the ground. What is the speed of the ball as observed by someone on the ground? The speed of light is c. V=500 Problem 2....

2. Now we are going to look at problem 1 again, but this time we are going to set the spaceship as the inertial stationary frame, meaning that the Earth is defined as the moving frame and traveling away from you. 1B:.8740 ; P = 2.058yr a. Using your answer from Ib as the speed of the moving frame, V, what is the speed of the Earth with respect to your spaceship? Using a Galilean Transformation equation for...

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...

9.1 Lorentz Contraction Objects traveling at relativistic speeds will appear to a stationary observer as shorter, as- suming that it is parallel to the direction of its motion. Using the equation for Lorentz contraction, find the following, where c is the speed of light: a) A spaceship is traveling with a velocity 0.8c. If it is 200m long in its rest frame (when the object is not moving), how long do you observe it to be? Assume that you can...
