for this car it will come off a ramp and will have to travel 3 meters and stop on a mark (where a dime is placed).
i have to design this car! It can't have any source of power, except the momentum gained from the ramp. It could have some form of breaking system!

LOOKING FOR SUGGESTIONS

For example, earth's gravity is two trillion times weaker than a black hole then put that in a percentage.ie. 000000000002

It's not metallic, I've smelled it. It has smell. However, I'm writing a book and it has a war scene. I need to know the specifics about the smell of blood. If anyone can offer a good response please do!

Charles Lutwidge Dodgson (1832-1898) was a mathematics teacher at Oxford University in England. You know this man better as Lewis Carroll (his pseudonym), the auther of Alice's Adventures in Wonderland.

Carroll enjoyed inverting things in his writing. Read this famous exchange between Alice and the Cheshire Cat:

"But I don't want to go among mad people," Alice remarked.
"Oh, you can't help that," said the Cat: "we're all mad here. I'm mad. You're mad."
"How do you know I'm mad?" said Alice.
"You must be," sad the Cat, "or you wouldn't have come here."
Alice didn't think he proved anything at all.

The cat justifies the statement "if you're here, you must be mad" by reversing the statements, saying "if you're mad, you must be here."

Explain why Alice doesn't agree with the Cat at all.

Yeah, so I have 2 other questions to answer as well.

1) Show that, if k is any real number, kx² + (3k+2)x +(2k+3) = 0

2) For what values of m does the equation have two equal roots?
x² - 15 = 2m(x-4)

Anyway, any help on how to do this work would be great, and very appreciated

I just don't know what it's all about. OK, I know that (dy)/(dx) is just the derivative of y with respect to the x, but it gets more complicated when it gets to the chain rule and implicit differentiation. I don't know what does this notation represent. In fact, I don't even know what does d stand for. Can someone please explain it to me in the simplest possible terms (I tried Wikipedia but I still don't seem to get it)?

There are two things. The speed at which gravity turns on and the strength of gravity. Like a ligh bulb, there is the speed at which the light turns on and its brightness.

So the most powerful sources of gravity known is a blackhole. The gravity is pulling things in a such a rate that light itself is sucked in so its safe to say that gravity in a black hole is traveling at the speed of light.

What would the speed of gravity be on a neutron star and earth?

You can convert the gravity to speed by knowing the strength of gravity.

What is the strength of gravity in a blackhole?
That variable would be the speed of light in gravitation because we know light can't excape it.

What is the strength of gravity on earth?
So what is the ratio between earth and the blackhole? Do some math skills that I am horrible at and you come to the conclusion at how fast gravity is.
