Relativity: Ato At-yAto 1-( Relativistic addition of velocities: u u'+v 1+ c2 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. Problem...

In Newtonian mechanics, velocities add in an intuitive way: so if a launcher that can launch a ball horizontally at 20 m launches a ball forward while on a car moving at 30 m/s, the ball is launched at 50 m/s relative to the ground (you could say u = vtu', where u' is the velocity of object within the reference frame moving relative to the "lab", u is the velocity of the object in the lab frame, and v...

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.

2. (30 pts) (based on Ohanian 11.41 homework problem) A woman of mass Mw and a man of mass MM face each other on a frictionless ice po standing still a distance L apart. The woman holds a ball of mass MB. Answer the following questions from our "lab' frame of reference, the perspective of someone at rest on the pond using an origin at the initial position of the woman and an x axis with positive x pointing towards...

Need help with these two problems. Thanks!
1. Relativistic velocity addition: Consider a universe in which Einstein's postulates and special relativity are valid but the speed of light c 300 miles/hour. A Kia with proper length L and a Bugatti with proper length 2L are racing. The Kia moves at a fixed radar gun. In the Kia's reference frame, both cars have the same length. What is the speed VB of the Bugatti with respect to the radar gun? speed...

Alice G LOO Bob Let's revisit the simultaneity problem from worksheet 11. To make things concrete, we'll include specific numbers. Bob is standing on the ground watching Alice go by in a high-speed train. As seen in Bob's reference frame, Alice is traveling to the right at speed v = +0.80c. As measured in Bob's frame, Alice's rail car is 12 m long. Alice is sitting in the exact center of the train car. At the instant that the Alice...

this is one question but with multiple choice questions,
sorry.
Problem 1 You're in a spaceship in deep space. Your engines are off, and you're far away from any reference points. a) You release a small ball from rest. The ball remains floating at rest in the same position where you released it. What kind of reference frame are you in? Is there any way to tell if you are moving at all? Let's designate your reference frame as S,...

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.

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.
