Science thoughts
« on: May 02, 2012, 07:20:11 AM »
hey guise i was wondering the other day what if

An airplane accelerates down a runway at 3.20 m/s2 for 32.8 s until is finally lifts off the ground. Determine the distance traveled before takeoff.

A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110 m. Determine the acceleration of the car.

A race car accelerates uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. Determine the acceleration of the car and the distance traveled.

jus wondering what your thoughts were

Christ, do you really need help with these problems? I mean really? This doesn't even qualify as pre-alegbra.

I'd recognize textbook problems from an 8th grade science class any day.

Also, your spelling needs work.

And I hope for your sake you aren't in school typing on your phone during a test because if you are, I'll find you and tell your teacher. You WILL be punished.

:( ur mean dave

Anyway, the reason I wanted to see if my reaction to 'totes not homework help lol" questions was typical


I mentor undergrads in Politics and I was asked if I wanted to have a discussion on whether 'The integration process has been too erratic to be explained by integration theories'. How much do you agree with this statement and why?

To this end I spouted a load of rubbish and left it at that.

Let's turn this thread into one about if an airplane will still achieve lift if accelerating on a conveyor belt going the opposite direction.  I say it will.

Are we assuming, like in most physics problems, that the airplane is accelerating in a vacuum?

Obviously not because the plane would not fit in a vacuum anyway, except maybe if it's a toy airplane.  And besides it wouldn't achieve lift with no air at any rate.

No, we would have specified a space shuttle. Why would an airplane be in space?

Space isn't a vacuum though. Besides, air planes can't accelerate in a vacuum.
