1 AnswerMathematics1 decade agoAngular velocity of precession?
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)

2 AnswersPhysics1 decade agoRelativistic alien rocketship?
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

2 AnswersPhysics1 decade agoThe relativistic mosquito?
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?

3 AnswersOther - Internet1 decade agoproof: inner product spaces?
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
