Suppose that, at t=6.00×10−4 s, the space coordinates of a
particle are x=255 m, y=35.0 m, and z=35.0 m according to
coordinate system S. If reference frame S′ moves at speed 1.41×105
m/s in the +x-direction relative to frame S, compute the
corresponding coordinate values as measured in frame.S′. The
reference frames start together, with their origins coincident at
t=0.
x' = ??? m
y' = ??? m
z' = ??? m

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.

A rectangle with coordinate system with axes x,y,z is rotating
relative to an inertial frame with constant angular velocity w
about the z-axis. A particle of mass m moves under a force whose
potential is V(x,y,z). Set up the Lagrange equations of motion in
the coordinate system x,y,z. Show that their equations are the same
as those in a fixed coordinate system acted on by the force
-grad(V) and a force derivable from a velocity dependent potential
U. Find U.

3. Consider the following two lines:
x = c + t, y = 1 + t, z = 5 + t and x = t, y = 1 - t, z = 3 +
t.
Is there a value c that makes the two lines intersect? If so,
find it. Otherwise, give a reason.

Consider the BVP or the steady-state temperature u(x,y,z) in the
airspace between two infinite (in the y and z directions) stone
walls that are perpendicular to the x-axis, and are 5 centimeters
apart from each other (ie the wall surfaces in contact with the air
space are 5 cm. apart), with the first (or left) wall located at
x=-1 cm. and the second (or right) wall at x= 4 cm, where ux = -10,
and u=100, respectively. Temperature is measure...

Relations and Functions
Usual symbols for the above are;
Relations: R1, R2, S, T, etc
Functions: f, g, h, etc. But remember a function is a special
kind of relation so it might turn out that a Relation, R, is a
function, too.
Relations
To understand the symbolism better, let’s say the domain of a
relation, R, is A = { a, b , c} and the Codomain is B = {
1,2,3,4}.
Here is the relation: a R 1, ...

???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...
