Radius. Sigh. I hate when I make stupid mistakes like that. Thank you all for your help.

I used 5.1x1018 kg for the atmosphere's weight and 4*π*12,742,0002 m2 for the surface area of the Earth. I got 2,499,684 kg/m2

In what units? I tried this with Earth's atmosphere and I didn't get the right answer.

By composition, I meant quantity of each gas.

Let's say I had the composition of an atmosphere, the mass of the planet it was on, and the diameter/density of said planet. First, what else, if anything, would I need to find the atmospheric pressure? Second, what would the equation for doing so be?

You are a lifesaver. Thank you.

Force is constant, yes. Can I ask what u represents in that equation?

Sorry, forgot to mention that in the initial post. Mass is 5.6664g, initial velocity of 0, final velocity is 100m/s, distance is variable, and time is 0.5s.

I need to figure out an equation for the following situation: A force will be applied to an object with a certain mass. When the object has moved a certain distance over a certain time, it will have a certain velocity. I realize I wrote that out like a textbook question, but that's just to make...
