The diagram shows an object of mass, m, and moment of inertia, I, rotating with angular velocity, w, on the end of a massless rod of length L.

As a result the system will rotate about the pivot point with and angular velocity, w'.

Show that w' = mgL/(Iw)

An alien rocketship travels at v=0.8c past the earth at midnight (rocket and earth time agree).

At 12:30am (rocket time) the aliens decide to shoot their laser gun (v=c) at earth but unfortunately when the laser beam arrives at earth it collides with a mirror and reflects straight back at them.

What time is it when the laser beam catches up with the aliens and blows up their rocketship?

Note that the aliens never stop or turn around they keep going at a constant v = 0.8c until the end

A rocket ship passes the Earth at the stroke of midnight with velocity v = 0.8c.

After a short nap the spacemen are awoken by a thud and arise to find, what appears to be, the remains of an extra-terrestrial mosquito on the windscreen.

Excited by their discovery, they radio the news back to Earth at 12:30am.

After receiving the news, Earth radio's back immediately to congratulate them.

What time do the spacemen receive their congratulations message?

when I receive an email from a yahoo mail I can bring up the full headers and see the senders IP address but when they come from gmail or hotmail all i get is their ip address and nothing about the sender

suppose u,v are non zero vectors in an inner product space

prove that

|| u/||u|| - v/||v|| || ≤ 2||u - v|| / max{ ||u||, ||v|| }

it has me stumped, i've been at it for days, but I know it can be proven

the first part of the question asked to prove that

| ||u|| - ||v|| | ≤ ||u - v||

which is easy to prove, so this can be assumed as well as triangle inequality, cauchy-schwarz inequality, etc etc if necessary

This person has at least 9 accounts and they don't like me for some reason

I had to hide my Q & A recently because all of my answers had 5 thumbs down and all of my answers in voting had 9 votes against them

It was too consistent to be a coincidence, there is definitely somebody out to get me

How can I deal with this person without knowing who they are?

Sn = the symmetric group of permutations of n elements

prove that

if K is a normal subgroup of Sn and K contains a transposition (a,b), then K contains all transpositions

it seems obvious but I'm not sure how to prove it

.

solve (d denotes the partial derivate)

(x+y)(du/dx - du/dy) = u with condition u(1+s,1 -2s) =1

where s is a constant and u = u(x,y)
