so tangent at x=2 for y=(x+2)^2 ... if U=x+2 then you had it partially right, you got the 2U which is the 2(x+2) ... but because you are substituting U in you have to treat U as a function which means you would have 2U(U')

I've been studying a few things related to this so I am not just asking a bunch of question's and yes it does related to a ppm, my idea would be effectively a ppm however at a point the container would weaken to the point of breaking and stop it, so it is not a true ppm. ... Since i don't have...

first i want to say that this is amazing and looks almost like a black and white photo and that i wish i could even come close to drawing something like that. now i have to offer one piece of criticism. You did the face so well and with so much detail that hair looks like it was an after...

im just wondering for just a magnet moving through an uncharged coil, the charge created is creating a force back on the magnet right?

ok so i know that there is force between a magnet and a wire with a current already in it. So tell me if I am misunderstanding, but then are you saying that that force also applies when the magnet creates the current in the wire?

as a rule of thumb the acceleration of gravity on Earth is 9.8m/s ... so unless they want you to do a lot of research i'd say that's it or 32ft/s

but it doesn't have to be dropped it can be pushed sideways

I know that a magnet passing through a coil will create a current in the wire. So what is stopping us from using magnets to power things?

TREBUCHETS RULE ... just sayin ... we made one in robotics. it is definitely worth it.

ok so for your average acceleration is just 20^2/radius which is going to be your magnitude. in order to find the radius you need to find the length of the arc. And because the car is traveling at a uniform speed you can just use a simple kinematic equation to find the arc distance...

Thanks for the explanation. :)

Homework Statement so this isn't really homework but I'm having issues putting it up anywhere else ... so at the first instant of acceleration, when it is changing from zero to another number ... doesn't that break the theory/law that there is no instanious increase or decrease in accel...

almost ... it is a(b)^t otherwise agree with that.

well it is in respect to t so if you can find the derivative of b^t than it is -(a(derivative of b^t))/((ab^t)+(1/c))^2 ... assuming that a, b and c are all constants

i don't really feel like number crunching to check if my idea is correct but for the most part i agree with how you attempted this and i would have started the same way. the difference i believe would be that if you factor in a ratio of their mass's. ... If you think of it as two separate...
