Question

In the earth's reference frame, a tree is at the origin and a
pole is at *x*=40km. Lightning strikes both the tree and the
pole at *t*=15*μ*s. The lightning strikes are
observed by a rocket traveling in the *x*-direction at 0.7
*c*.

Part A: What are the spacetime coordinates *x*′tree,
*x*′pole for these two events in the rocket's reference
frame? (x'tree, x'pole) km

Part B: What are the spacetime coordinates *t*′tree,
*t*′pole for these two events in the rocket's reference
frame?

1. In one inertial reference frame, an electron is observed
traveling with a velocity of magnitude v in the positive
x-direction, where v is 0.6c. What are the momentum and total
energy of the electron in that inertial reference frame in terms of
v and the rest mass of the electron? What are the speed, momentum
and energy of that electron as measured in a reference frame that
is traveling at a velocity of magnitude v/2 in the positive
x-direction?...

A muon is created 65 km above the surface of the earth. In the
earth's frame, the muon is traveling directly downward at
0.9999c.
Part A In the earth's frame of reference, how much time elapses
between the muon's creation and the time it reaches the
surface?
Part B
Use time dilation to determine, in the muon's frame, how much
time elapses between the muon's creation and the time it reaches
the surface.
Part C
In the muon's frame of...

Inertial reference frame A and inertial reference frame B have
x-axes that point in the same direction, and reference frame A
moves relative to reference frame B at a constant velocity of 0.680
c in the +x-direction. These reference frames record the times and
positions of the following two events.
A space transmitter is destroyed in a sudden explosion.
The on-board computer on a space satellite suddenly shuts
down.
According to reference frame B, the computer shutdown occurred 7.51
x...

ane sets up two mirrors in her reference frame where mirror A is
located on the x-axis 100 m from the origin and mirror B is located
on the y-axis 100 m from the origin. She then causes a light
source, which is located at the origin and emits light uniformly in
all directions, to flash once at t=0.
(a) As measured in Jane's inertial frame, what is the time at
which the light flash reaches mirror A?
(b) As...

16. A rod lies parallel to the x axis of reference frame S,
moving along this axis at a speed of 0.567c. Its rest length is
2.39 m. What will be its measured length in frame S?
17. In a high-energy collision between a cosmic-ray particle and
a particle near the top of Earth's atmosphere, 131 km above sea
level, a pion is created.The pion has a total energy E of 1.61 ×
105 MeV and is traveling vertically downward....

Consider the case of two different frames of reference. One
frame is stationary, the other is moving at a speed of 0.6 c in the
+ z direction. If an event occurs at position x = 1.9 light years
at time t = 55.6 years in the moving frame, what x position, in
light years, would be recorded for the event in the stationary
frame. Give your answer to two decimal points.

What tools could AA leaders have used to increase their
awareness of internal and external issues?
???ALASKA AIRLINES: NAVIGATING CHANGE
In the autumn of 2007, Alaska Airlines executives adjourned at
the end of a long and stressful day in the
midst of a multi-day strategic planning session. Most headed
outside to relax, unwind and enjoy a bonfire
on the shore of Semiahmoo Spit, outside the meeting venue in
Blaine, a seaport town in northwest
Washington state.
Meanwhile, several members of...
