    Finding Tensions and Accelerations with Moveable Pulley

    Sorry for so many accelerations - I think I realized now that you could just set up your axes for your coordinates system differently on each side of the string, rather than just set up one axis and change the sign of the acceleration (right now I treat everything down as pos, up as neg). I...

    Finding Tensions and Accelerations with Moveable Pulley

    (Moved to the homework section by moderator.) Please see the image. My confusion is with a moveable pulley. Can I just do my balances on both 1kg and 2kg masses disregarding the acceleration of the pulley? Here are my eqns. Object numbers 1, 2 and 3 denote the 3kg, 1kg and 2 kg weights. 4 is...

    Rewriting a base; Formula of a Reciprocal Function

    Thanks Wukunlin, but I know I can combine e with its exponent. Let me just replace that "x" with "t". Ie: y = 6e^0.4t can be written as y = 6(1.4918...)^t - I need to find a way to get the "t" next to the base, and somehow get the base as the exponent - in the form y = at^b. I'm just confused...

    Rewriting a base; Formula of a Reciprocal Function

    Homework Statement I have a function, y = 6*e^0.4x. How would I convert the regular form, y=a*e^bt to the form y= at^b? Homework Equations y = 6*e^0.4x The Attempt at a Solution I've tried to take the log of both sides, but if I do that, then "y" becomes a log, and I can't...
