A 0.400 kg toy truck moving at an initial speed of 0.100 m/s collides head-on with a 0.300 kg toy car at rest. The collision is elastic. Find their final speeds and directions.
a. v1 = 0.100 m/s v2 = 0.0 m/s
b. v1 = 0.0 m/s v2 = 0.100 m/s
c. v1 = 143 m/s v2 = 114 m/s
d. v1 = 0.0143 m/s v2 = 0.114 m/s

I am working on a desert wasteland reclamation project and need a technology to use windpower to pump fresh (read brackish) water from very deep boring. There is no electricity and the community involved is too poor to pay for any expensive technology. But there are good mechanics who can make a suitable wind turbine pump if someone provides drawings/details.

One possible solution is Rotary Borehole Pump. But we do not know how to make it. Can someone help, please?

assume you can observe, built up structures. remember the speed of light, ancient civilizations here on earth, and the interaction and impact that the life form(s) (our case, human) may have played. all your observations are done with massive telescopes.

A Centipede (Scolopendra heros)

A Desert Hairy Scorpion (Hadrurus arizonensis)
http://bugguide.net/node/view/13974

A Desert Tarantula (Aphonopelma chalcodes)
http://bugguide.net/node/view/63705


All three are common to the south western United States.This is not some stupid question, I want to see if you know which of the three would win if they all were to fight, Im looking for an answer than incorporates all of their abilities and natural defences. This could be more of an ethological question rather than brutality.
Best answer with the best descriptin wins 10pts!

I'm a left-handed girl and wonder why most people are right-handed... isn't that kinda weird?

Anyway, do you know any left-handed but famous/succesful people and celebrities in this world?
(I only know Katharine McPhee, runner up on the American Idol 5. She's left-handed girl also!!)
