A car traveling at 91.0 km/h approaches the turnoff for a resturant 30.0 meters ahead. If the driver slams on the breaks whith an acceleration of -6.40 m/s^2, what will be her stopping distance? I'm having trouble putting this into a formula and making it work.

the law of conservation of mass states that matt can not be created nor destroyed, only changed from one form to another. this being said, can you think of any scenarios where the Law of Conservation of Mass does not apply?


take a stab at it...thanks

i am making a model of alluminum. i think that i have to show the electrons, protons, and neutrons, but im not sure. my teacher doesnt really tell us anything. i am not really sure how i should make this. could someone help me out? i have styrofoam balls and a posterboard but i dont know how to make it with a posterboard, so i was just gunna make a model and not put it on the poster board, but i dont know how to go about this. i dont knwo what wire to use and i dont know if i should paint it and i dont know how to hold it together and i dont really know anything. if you could give me any help i would appreciate it, it would be nice to see some examples of either yours or just of models you found online, and a website on how to build it would be great too. please and thanks.

Could i find out the distance (just the distance, not the position) from the center of an atom to the electron without using Bohr's model of the atom, nor the strodinger equation?

because i think i came up with an equation that could find the distance (radius) using the energy levels such as ionization energy, work function, or simply hv=E.

and again this has nothing to do with Bohr or Strodinger equations.


P.S i have never seen an equation like the one i came up with.
the electron radius emerges naturally in my equation.

the solutions are the SAME as if I was using the Bohr model of the atom...

Here is the question I am having troubling figuring out how to solve.

A recent study by the Island Resort Taxi Drivers Association showed that the mean fare charged for service from the beach to the airport is $18.00 and the standard deviation is $3.50. We select a sample of 15 fares.

a) What is the likely hood that the sample mean is between $17 and $20?
b) what do we have to assume to make the above calculation?

Any help just to get me started would be greatly Appreciated

I seem not to be grasping the concept of "implicit differentiation". I already know the power rule, product rule, quotient rule, and chain rule.

For example, a problem in my calculus book asks me to find the derivative of x * y + 2x + 3x^2 = 4 by (a) setting the equation equal to "y", and (b) using implicit differentiation.

I already can solve part a of this problem, but i don't know how to do part b. Here's what I've got:

x * y + 2x + 3x^2 = 4
(d/dx)(x) * (d/dx)(y) + (d/dx)(2x) + (d/dx)(3x^2) = (d/dx)(4)
1 * (d/dx)(y) + 2 + 6x = 0

Then I tried to follow the book's example, and did:
(d/dx)(y) = (d/dy)(y) * (d/dx) = 1 * (d/dx)

So, how does this implicit differentiation work and what do I do now, considering I'm correct?
