    Ask a Stupid Quetion Get a Stupid Answer

    he was attacked by a flock of birds while cleaning his bathroom sink out If you named a burger chain Heisenburger, would you be able to tell what was in the food and how much it cost at the same time?

    Finding kinetic friction coefficient from angle, distance and time

    Yeah, I caught that when I checked it over, but thanks, because you've been a real help! :biggrin:

    Finding kinetic friction coefficient from angle, distance and time

    Ah, I think I see it now. Thanks! :biggrin: Would this be correct: mgsin\theta - \mu mgcos\theta=ma mg(sin\theta - \mu cos\theta)=ma g(sin\theta - \mu cos\theta)=a \mu g +g(sin\theta - cos\theta)=a \mu +sin\theta - cos\theta=a/g \mu=a/g -sin\theta + cos\theta \mu=2\Delta...

    Finding kinetic friction coefficient from angle, distance and time

    I could express it as F_N=mgcos\theta right? Then I could substitute it for F_N in F_f=\mu F_n After rearranging to solve for μ, it would be \mu=F_f/mgcos\theta Substituting the fifth line of my original solution for F_f would give me \mu = \left(2\Delta d/\Delta t^{2} - g sin...

    Finding kinetic friction coefficient from angle, distance and time

    There is no applied force, do you mean net force? Also, I'm looking for the coefficient of friction, not the force of friction, otherwise I would have stopped at the line Ff = 2Δd/Δt² - g sin θ

    Finding kinetic friction coefficient from angle, distance and time

    Ok, I realize that since μ is a constant, it shouldn't be mass dependent. I also know that since there is no acceleration in the perpendicular direction, the normal force is opposed by, and has a magnitude equal to, the perpendicular component of the force of gravity. I've expanded this to mg...

    Finding kinetic friction coefficient from angle, distance and time

    [SOLVED] Coefficient of friction on an inclined plane Homework Statement The problem I have is to determine the coefficient of kinetic friction between two wooden objects, a block and a ramp, using the fewest measurements possible. The initial velocity will be 0. I can measure the angle of...
