    Anonimity: Time to take the internet back.

    There are a few other really good Firefox add-ons I use that I wanted to mention. DoNotTrackMe is an add-on which blocks all sort of online trackers from tracking you. https://addons.mozilla.org/en-US/firefox/addon/force-tls/ is not a privacy add-on per se, but it encourages https...

    Rolling, Both Slipping and Nonslipping

    I see. This makes sense. Thanks once again!

    Rolling, Both Slipping and Nonslipping

    Didn't you state the condition already? v = rω, which is what I used, except that according to you the ω should be the magnitude (absolute value), which makes sense. I guess I didn't think about the fact that I was setting two different unit vectors equal to each other! Thanks for the help...

    Google's challenger, Bing it On

    I've been using DuckDuckGo for a while, and I generally like the results. I also like that it stores a lot less data about me than Google does...

    Rolling, Both Slipping and Nonslipping

    Homework Statement A cylinder of radius r, mass m, and rotational inertia 1/2mr2 slides without rolling along a flat, frictionless surface with speed v0. At time t = 0 the object enters a region with friction (with coefficients μk and μs), as shown above. Initially the cylinder slips...

    Finding x for a spring using energy equations

    Ah. This makes sense now! Thanks!

    Finding x for a spring using energy equations

    Homework Statement This isn't a homework question, just something I've been thinking about. If given a situation in which mass m is hung on a spring with constant k, I know you can set the spring force equal to the weight of the mass to find how far it stretches. Is there a way to find how...

    Velocity of ball rolling down ramp

    I have part of a response ready to send, but as I was working out the problem to make sure I was getting the correct answer, I noticed something odd. When I got the final answer, it did not match with the answer you gave. Are you sure that the answer you posted is correct, or is it possible it...

    Help with Connecting TI89 Titanium to Computer via Data Cable

    Are you plugging the device into the same USB port it was plugged into when you first installed the drivers? I know that sometimes on Windows computers I've had a problem where I installed the drivers, but they only worked if the device was plugged into the same port it was originally.

    Computer needed for engineering college

    I don't know what you are planning on studying, but I know some places recommend/require having a Unix-based operating system if you are studying computer science. In that case, you could either get a laptop which you could install some sort of Unix OS on, or you could just get a Mac if you...

    Manipulate Matrix Output (TI84+)

    If you want to change the output into a fraction, I believe there is a function which can be found in the Math menu (I think it is the first option) which looks something like ->Frac. This function obviously won't work for irrational numbers, and it's possible that it doesn't always work for...

    What is the mass's total acceleration at the bottom of its swing?

    The method is correct. Now you just need to check your units to make sure that they match up with the units given in the multiple choice answers.

    What is the mass's total acceleration at the bottom of its swing?

    Just to explain this a little more to hopefully help riseofphoenix understand it: you can't plug in the mass of Jupiter to find the force Jupiter exerts on the object. Doing so would be like trying to find my weight (also known as the force that the Earth exerts on me) with the equation w =...

    What is the mass's total acceleration at the bottom of its swing?

    I believe this is correct. In regards to how you should go about finding the gravitational acceleration you would feel on Jupiter, keep in mind that you are supposed to be finding acceleration. You look like you were solving for the force Jupiter will exert on an object, not the acceleration...

    Calculators TI-89 won't factor or expand polynomials

    I don't know what the problem is, but is it possible that you have something (maybe a matrix?) stored in the variable x? If x has something stored in it, the TI-89Ti evaluates the expression as though the stored value were there in place of x rather than evaluating the expression symbolically...
