If the translational rms speed of the water vapor molecules (H2O) in air is 676 m/s, what is the translational rms speed of the carbon dioxide molecules (CO2) in the same air? Both gases are at the same temperature. So what I have so far... VrmsH20 = squareroot of 3RT/mCO2 VrmsCO2 =...

Ahhh...! I think I got it, thank you very much!

I do understand that it's not the height that is going to infinity, but instead it's the velocity that's going to infinity. However, I don't understand how it can to infinity because the velocity should slow down at some point, but before the ladder hits the ground. However it's not the...

Calculus Problem?? Suppose that we have a ladder 20feet long, leaning against a wall. Let x be the distance from the wall to the bottom of the ladder and y be the distance from the ground to the top of the ladder. a. What will be the value of dy/dt when the top of the ladder hits the...

I got it! Thanks for your help! But can u guide me in a direction with the second one? PLEASE!

Yep, so i took 88.0 rad/s and divded that by 5.4sec and got a angular acceleration of 16.3. Then took that times the I, and that equaled 13.85 for the torque. Now what formula do I use? Is it... (Force * radius = I * angular acceleration) to find the Force applied to the brake? and then...

Mainly it's the fact that I really don't understand this stuff at all. I tried different ways to look at it, but all of them don't make sense. I've been staring at this for hours now and still i can't get anything that makes sense, it's really frustrating. I know you guys don't show us how to...

I have a couple questions could someone help? I tried everything and I just don't understand what's going on. Thank you sooo... much! :D 1)A cylinder is rotating about an axis that passes through the center of each circular end piece. The cylinder has a radius of 0.0600 m, an angular speed...
