I have a few problems for a review section in my book for a test comming up soon. i am confused on a few problems and was wondering if some1 could help please? 1.) The Axis is horizontal; the parabola passes through the points (0,4), (0,-1) and (6,1) I am very confused on this problem...

ok so for U for example, U in form i,j would be 1i + 1j and 2i + 4j ?? I am lost a little or does this mean 2i + 1i = 3 and 4j + 1j = 5 so U(i,j) = (3,5) ??

vector help asap please! I have a problem that says define the i,j form of a vector and write the following vectors in i,j form u = P(1,1) to Q(2,4) and v = P(6, -3) to Q(7,0). I looked all through my book, and cannot find a definition for the i,j form of a vector ( i checked...

Ok, I have a final in Pre-Calc comming up, and I am still a bit confused on finding asymtotes (vertical, horizontal, and slant) could someone help me with equations i can use to find the asymtotes or how i do? I am just really confused. Heres the problem. Find the vertical asymtote(s): F(x)...

Ok, I have a final in Pre-Calc comming up, and I am still a bit confused on finding asymtotes (vertical, horizontal, and slant) could someone help me with equations i can use to find the asymtotes or how i do? I am just really confused. Also, I am having trouble with finding a fourth degree...

Im Having problems with 2D- curved track velocities. The question is...Find an Equation to find the velocity final of a car with mass - m going down a curved track with a coefficient of Friction - Uk The track is height - h above the ground and has an initial Velocity of Vi...so basically...

well, i can get the angle of the track, and possily the length of the arc, but i do not know how to get the radii, and how does it remove energy? turn it into heat? i could show you the problem on excell if that helps :confused:

Ok, I am still confused, so let's get a hypethetical question... 1.) The coaster weight is 6400 kg, and is released from rest at a height of 95.8 meters. FInd the Initial energy after the coaster travels 20 meters distance and has a height of 7.3 meters, and find the Velocity at the same...

So initial energy is the same as total energy?and centripetal acceleration matters because the track moves up and down, creating g-forces.. I am still very confused :confused: :confused: To clarify more, The roller coaster is like going down and up hills. Except the hills can change so height...

Ok...i am confused on some equations..please help me get a start, I am not asking for the answer, just something to go off of please :smile: So your on a 2-Dimensional Roller coaster, and you start at a height of H with an initial velocity of 0 m/s and a total distance of 0 m The track...

But what about Initial energy and speed? how do I get them without having Total Energy?

yes, Think of a track that goes up and down at random points...thats what its saying...so what is the speed with Centripetal acceleration added..I am still very confused..because none of my equations are working :confused: :cry:

I am having some problems with equations for a problem. The problem isn't really a question, it's more of finding equations to make something work. Basically, It is a graph on Microsoft Excel, that resembles a 2D track. The track has variable points that you can change, to increase height...

is there a website your doing all that on? or how do you get that font type/style

Oh, ok, i just worked it out and got 62.8 meters for the circumference. Is that what you got? ( I hadnt tried to find circumference or velocity, just going with his numbers )
