    Calculating the Equation of a Circle Tangent to x=sqrt(y) at (10,2)

    yeh that's right... first of all,, thanks to the replies that "somehow" help me and,, i hope that no arguing of nonrelated things will be done in my thread... anyways,, i already solved the problem in my own,,, jst few distance formulas dont question the homework helpers,, let them...

    Calculating the Equation of a Circle Tangent to x=sqrt(y) at (10,2)

    ok,, thanks to all... the C is (10,2) given by my prof for the purpose of self-checking our answers.. we are asked to find the solution in getting the equation of the circle.. ive tried solving it by letting C(x,y) and using systems of equations and i got x = 10 but my y variable always...

    Calculating the Equation of a Circle Tangent to x=sqrt(y) at (10,2)

    ok,, the (10,2), the center, is given as a hint by my prof,, for the purpose of checking our answers... we are asked to find the equation of the circle,, in general or center-radius form.. i've tried solving it,, i represented my C as (x,y),, i used systems of equations and i got x=10...

    Calculating the Equation of a Circle Tangent to x=sqrt(y) at (10,2)

    equation of a circle... a circle passes to points (2,0) and (18,0) and tangent to the graph of x=squareroot of y(half parabola)... the answer is supposed to be C(10,2) can you help me in finding a way to solve this?? please help me to know the exact procedure on doing this... thanks...

    Plase any one crrect my answer

    ok,, i think the answer in number 2 should be E,, because the 2 spheres have same diameter,, so same effect of air resistance,, they were dropped at the same time and have same effect of g,, so acceleration is the same...:cool: i got the same answers on everything but my velocity in number 7...

    Solving Muon Motion: Stopping Distance

    hmm,, thanks to all! i just got home from school... and u know what?? there's something wrong at the given! the acceleration is not that low... my prof's mistake! thanks again

    Solving Muon Motion: Stopping Distance

    i've used the 2.2 microseconds lifespan... i always get 11m displacement.. pls help me to get an answer closer to 0.1m anyways. this is just mechanics, i want to know why my prof's answer is 0.1m i'm afraid I'm running out of time,, i really need this asap... thanks for ur answers! pls...

    Solving Muon Motion: Stopping Distance

    hahaha... thanks, but i want to know the "rightest" answer because there will be a possibility that I'll find "different" lifespans.. please help.. i really need it... thanks

    Solving Muon Motion: Stopping Distance

    Homework Statement a muon moving in a straight line enters a region w/ speed of 5 x 10^6 m/s. it then slowed down at a rate of 1.25 m/s^2. how far does the muon take to stop?? Homework Equations 2ad + square of initial velocity = square of final velocity The Attempt at a...
