According to observer O, two events occur separated by a time interval Δt=0.48 μs and at locations separated by Δx=47.8 m. (a) According to observer O', who is in motion relative to O at a speed of u=0.950c in the positive x direction, what is the time interval between the two events? Answer: 1.052 μs (b)What is the spatial separation between the two events, according to O'? m

Only need part c for the velocity in the y direction
An observer is stationary in the inertial system S. A car is moving in the x- direction with speed V with respect to the observer in S. The driver of the car is stationary with respect to the car, and thus the driver is in a different inertial frame S. The passenger of the car takes out a baseball, opens the sunroof of the car and throws out the...

Observer O sees a red flash of light at the origin at t = 0 and a blue flash of light at x = 3.19 km at a time t = 7.56 μs. What are the distance and the time interval between the flashes according to observer O', who moves relative to O in the direction of increasing x with a speed of 0.630c? Assume that the origins of the two coordinate systems line up at t = t' =...

An observer on Earth sees Planet X to be stationary and also sees a rocket traveling toward Planet X at 0.5c. The rocket emits a pulse of light that travels outward in all directions. According to an observer on Planet X, how fast is the light pulse traveling toward them? a) 2c/3 b) c/2 c) 2c/3 d) 5c/6 e) c

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 see the entire...

Several steps to one question.. any help is appreciated!! a) A certain space ship is measured to be 80 meters long when it is at rest. How long is it measured to be by a stationary observer if it is traveling at 80 percent the speed of light? b) On the same spaceship as above, an astronaut watches a movie which is 2 hours long. How long does a stationary observer observe the movie to last for? c) Find the...
Two rockets A & B fly past an observer. "A" moves at constant speed 1000 m/s relative to ground, "B" moves at constant speed 1000 m/s relative to ground and opposite of rocket A. Rocket A sends light opposite to where it is heading.
You are standing on the ground observing the sky. Two spaceships A and B fly past you. Spaceship A is moving at a constant speed of 1000 m/s relative to the ground. Spaceship B is moving opposite to A at speed of 1000 m/s relative to the ground. Spaceship A fires a strobe light that sends out a pulse of light opposite to where it is heading. a) What is the velocity of spaceship A relative to spaceship B? b) What is...

Let two events occur at equal distances from an observer (O). The observer claims that two events will be simultaneous if light emitted from each event will reach me at the same time. Show that (maybe by drawing a picture) an observer (O') moving with respect to O will observe that these two events are not simultaneous. If two signals (say, from points A and B) reach observer O' simultaneously, what is their time sequence, as measured by O?
