9.1 Lorentz Contraction Objects traveling at relativistic speeds will appear to a stationary observer as shorter,...
Relativistic Length Measurements 4.7. Compute the contraction in length of a train 1/2 mile long when it is traveling at 100 mi/hr. Ans. 5.58 x 10-15 mi = 3.52 x 10-10 in. 4.8. At what speed must an observer move past the earth so that the earth appears like an ellipse whose major axis is six times its minor axis? Ans. 0.986c 49. An observer O' holds a 1.00 m stick at an angle of 30° with respect to the...
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...
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)...
pre Come HOMEWORK due Weds. Spaceship at relativistie speed - Timer Notes Evaluate Feedback 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 1255 m. What is the speed of the spaceship in terms of the speed of light? Hints: Objects moving at relativistic speeds shrink in the direction of motion. This is the so called...
Question I need answered is bold faced here: Relativistic Mass Still standing in the same spaceship... With respect to an observer in a given frame of reference, how fast would the spaceship have to move in order for your [moving] mass to be double your resting mass? From your perspective, what will be your mass on board the spaceship? In the last two weeks we have investigated time, length, and mass at very high velocities. Identify the unifying physical principle...
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....
