dude, I know I'm thin but I DO have SOME mass

Dude, if you had some ass you wouldn't be asking us how to get it.
Also, if you go with Massive Attack avoid Mezzanine. Elisabeth Fraser has a beautiful voice, but it only works if you're mackin' it slow stylee.

I'm glad I don't have to watch Turtle say words like "mackin'" or "stylee" in RL.

The real question is will the train meet the cheetah first, or will the cheetah meet the train first? Either way, once we open the box, we'll find out.

More to the point, if the cheetah can run faster than the train, does he need a ticket?

the answer you are looking for is 50kg.

F = m * a
F = vertical force exerted downwards (also known as "weight") SI unit = N (Newton)

m = mass of the object (commonly mistaken as the "weight") SI unit = kg = Kilogram (hence the confusion that people think when they talk about kg they are discussing weight, but scientifically they aren't)

a = accerleration due to gravity, in this case we will just call it 10ms^-2, it is this acceleration that gives bodies of mass their - "weight"

so
500N = m * 10
m = 500/10
m = 50kg

- people are correct that for a full look at the problem we will probably need to draw what are called "vector diagrams" to be sure that the components (such as horizontal, vertical and things at strange angles) are taken into consideration... but I am guessing you need the answer 50kg. the rest of yous can go home!
-------------------------
velocity = sqrt ( 2 ( pressure_std - ( 500N + mass_window * gravity_acceleration ) / area_window ) / density_air )

why i am having so much trouble checking the dimensions of the above eq

Because you suck ?

For future reference, you can mooch off the cleverness of this guy when you get yourself into jams like this one:

(http://hyperphysics.phy-astr.gsu.edu/hbase/hph.html)

Among other things, it's got automatic conversions, e.g., Kg -> Newtons: (http://hyperphysics.phy-astr.gsu.edu/hbase/mass.html#mas) Mass and Weight (just over half-way down); as well as online-solving equations for just about everything you'd probably want.

Your problem might involve (http://hyperphysics.phy-astr.gsu.edu/hbase/woang.html#waa) Work with force at angle or (http://hyperphysics.phy-astr.gsu.edu/hbase/vsca2.html#vsc4) Work as a Scalar Product, or maybe just, uh, (http://hyperphysics.phy-astr.gsu.edu/hbase/force.html#defor) force? It's probably just (http://hyperphysics.phy-astr.gsu.edu/hbase/vect.html#veccon) vector addition of the forces you want. Maybe some analogy to (http://hyperphysics.phy-astr.gsu.edu/hbase/caba.html) this? Well, it's in there somewhere.

I hope you get that magnet down ... Keep blowing!

But you're worse off for not actually watching him mackin' it slow stylee in real life.

Where are you guys pulling this Windspeed -> Pressure increase stuff from?

Can't seem to even find regular air viscosity on HyperPhysics.

Also, shouldn't wind decrease pressure rather than increase it?
