1. ### Transfer of Heat Question

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 =...
2. ### Calculus Problem?

Ahhh....! I think I got it, thank you very much!
3. ### Calculus Problem?

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...
4. ### Calculus Problem?

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...
5. ### Rotational Dynamics Questions

I got it! Thanks for your help! But can u guide me in a direction with the second one? PLEASE!
6. ### Rotational Dynamics Questions

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...
7. ### Rotational Dynamics Questions

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...
8. ### Rotational Dynamics Questions

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...
