Is rise over run the way you find slope?

Write an equation of a line with a slope of 0 and passing through the point (5,4). Write an equation of a line with an undefined slope and passing through the point (-2,4). I know how to do this type of thing but these two questions have stumped me. If the slope of the first one is...

:rolleyes: The two conducting rails in the drawing are tilted upwards so they make an angle of 30.0° with respect to the ground. The vertical magnetic field has a magnitude of 0.048 T. The 0.22 kg aluminum rod (length = 1.6 m) slides without friction down the rails at a constant velocity. How...

urgent help - finding what slope means Suppose a student is given position-time data for a cart which was known to have an initial velocity of zero. if the student plots the fifth root of time (t^1/5) on the y axis, what variable should he plot on the x-axis so that the resulting graph is a...

Suppose a student is given position-time data for a cart which was known to have an initial velocity of zero. if the student plots the fifth root of time (t^1/5) on the y axis, what variable should he plot on the x-axis so that the resulting graph is a straight line? how is the slope of the line...

here was the original question. in the design of a super market, there are to be several ramps connecting different parts of the store. cusomers will have to push grocery carts up the ramps. An engineer has done a survey and found that almost no one complains if the force require is no more that...

I got this problem: A ball is rolled up a constant slope with an initial velocity of 11.0 m/s and after 9.3 s the ball is rolling down the slope with a velocity of 7.3 m/s. What is the acceleration of the ball on the slope. Here's what I tried: I divided the problem in 2 for the ball going...

Im in gr.12 and my teacher gave us a dry lab to do. I have all the information. But there's a question that i can't answer. So can you please help me. The purpose of this lab is to determine the relationship between the resistance, the length and the diameter of an electrical conductor...

*Edit Note: I apologize if this belongs in the homework or classic physics sections; I have been in a real hurry to post it, and I just assumed problem which is meant for real life application would not belong in a place for schoolwork, so I put it in the general board without anything more than...

In a problem concerning Mechanics/Dynamic Motion, I am asked to find the acceleration net of an unidentified mass. I am given mu (.1) and the slope of the incline (38 degrees). After searching through my notes and as well as online, I cannot seem to find a way to determine the magnitude of the...

hi peeps, can u guys help me with this question: A wheel weighing 40kg is rolling down a hill, inclined at 30 degrees. After reaching a speed of 5m/s, the wheel falls over on its side and begins sliding down the hill. 1. if the coefficient of friction for the sliding wheel is 1.00...

I am really stumped! Using only Trigonometry, I am suppose to calculate the amount of force that is needed to keep a 2000 lb car from rolling down a ramp of 30 degrees. Am I on the right track when I say: x=2000cos 30? Then what?

There is a 760N heavy car on a plane which is inclined to the horizontal at an angle of 6.8 degrees. Calculate the forward driving force which accelerates the car down the slope. I know the answer is 760sin6.8. I know that the forward driving force has a direction which is parallel to the...

Suppose that there's a flat 3-d plane with points A,B,C,D. The midpoint is X. How do I find the equations for each of the points if the plane is slightly warped (meaning, that its sort slightly of bent). If I were to find the slopes on each side of the plane, would it matter that it's slightly...

Here's the problem: detrmine DE giving the slope of the tangent line at point (x,y) for the given family of curves: 2cy = x^2 - c^2 Here's what I have: slope of this curve: y' = \frac{x}{c} So, then the slope of tangent line is negative inverse: y' = \m \frac{-c}{x}...

An eraser slides down a slope of height 1m that makes an angle of 35 degrees with the ground. It takes the eraser 1,8s to do this. Find the coefficient of friction. I have no clue how to do this. I've not been able to solve any of the equations I've tried, because there is always the mass of...

On flat ground, a driver takes 0.6 seconds to react to something signalling him to stop. When the driver hits the brakes, the car decelerates at 6 2/3 ms-2. The driver is now driving down a long slope at 10 degrees to the horizontal. When a beam of light is flashed on him, he immediately...

1) Find the slope a) (3.14)/6 b) 135° c)60° 2) Find the angle of inclination of a line with the given slope a) m=-1/2 b) m=1 c) m=-2 d) m=57 how do u do these questions?

For some reason, this isn't working out. The Arhennius equation, k = A*e^(-Ea/RT) I have tables of temperature and k. The book says just calculate it by having the x-axis be 1/T and y-axis be ln(k) Ok, take Ln of both sides ln(k) = ln(A*e^(-Ea/RT)) ln(k) = -Ea/RT + ln(A) Oh, that...

I wrote down the notes from class, but when I tried to do the homework, I am not even close to the right answers. The formula I wrote down is: \frac{-1}{(x)(x+h)} Apparently that's wrong. Anyone know what it's supposed to be?

:smile: My question says f(x)=(-5/7)x-3 determine the slope of f^-1(x) without finding the inverse. I think the answer is the slope of f^-1(x)=(-7/5)x Is this correct?

Hey ppl, If you have a man pushing a box up a slope with a horizontal force at constant speed from distance a to b, can one assume the Work done by friction to be zero all the time since velocity is constant? or can one assume W(neoconservative)=change in U(gravitational PE) only, with...

I'm new at this, so I hope someone can help me. I have AP Calculus and need some help on a problem... Given the curve x+xy+2y^2 = 6 Find the coordinates of all points on this curve with slope equal to the slope at (2,1) Any help is much appreciated!

I got this problem for physics and i can't seem to get it, it goes like: A projectile is launched at an angel of 40 degrees with an initial velocity of 100 m/s. One hundred meters away is the beginning of a hill that slopes upward at an angle of 20 degrees. The projectile strikes the hill a...

A football is kicked into the air at some angle theta and lands down field. Ignoring air friction, draw a rough plot of its speed versus time. Is the slope of the curve the acceleration? Explain. I think the slope of the curve is the absolute value or the magnitude of acceleration, isn't it?

I'm still having trouble with figuring out slope fields. If I have a function dy/dt= f(t,y), how would I go about graphing the slope field for my solutions without the use of a calculator. An example would be how would I graph the slope field of dy/dt = t^2-t and dy/dt = y^2? Thanks.

I always thought the M stood for something like meta which was like greek for change or something.. but I am not sure that is right =-/ Can someone also refresh my memory regarding the meaning of b in the y intercept fomula?.. why did they decide to set it to be.. I think there is a reason...

2. Two mountains are at elevations of 850m and 750m above the valley between them. A ski run extends from the top of the higher peak to the top of the lower one, with a total length of 3.2km and an average slope of 30 degrees, a) A skier starts from rest on the higher peak. At what speed will...

hey firstly, I am not so certain this is the correct place for this thread, sorry!feel free to move! basically, if you look at the file attached, I am trying to find friction up the slope, but i cannot do it, and i can't see how you will do it, so if anyone could shine some light, i would be...

A boy is traveling down a slope on a sledge. The boy and the sledge have a total mass of 60kg and are traveling at a constant speed. The angle of the slope to the horizontal is 35 degrees. There are 3 forces acting on him, the weight of him and the sledge acting straight down W, the push from...

19) An Olympic skier moving at 20m/s down a 30degree slope encounters a region of wet snow, of coefficient of friction, .74 a. How far down the slope does he go before stopping? I know the answer is 144m, but how do I get there? b. How much mechanical energy is lost in this process...

Hi, I was looking at a problem from an old test and I got confused about something. Q. Find the slope of the tangent line to the given curve at a given point: y = x(x^2 + 3)^1/2 ; P(1,2) S. First I found the derivative: [(x^2 + 3)^1/2] + [(x^2)(x^2 + 3)^-1/2] Plugged in the...

I just don't get it! We're learning about finding the slope of a line. And I don't get any of it, so can someone explain it to me? I could find the slope through a pair of points: C->1(2,1) 1-1 =0 D->2(3,1) 2-3 =-1 and the answer is 0...(note that this is algebra((or...
