Oh, Remember to divide your dtheta/dt by 60 to get radians per second change.

Ok, define the 1/2 mile part to be x. Now set up the equation tan(theta)=x/1. Differentiate and get sec^2(theta)*dtheta/dt=dx/dt. Solve the triangle at the time when x = 1/2, and you find that the hypotenuse is sqrt(5)/2. Solve for sec(theta)^2. Plug in your 40 mph for dx/dt and rearrange...

Well, one of your problems is that you do not have enough variables. Try defining the 1/2 miles part x and set up a tan theta= x/1 equation to differentiate.

Homework Statement A man 6 ft tall wlaks at a rate of 5ft/s away from a light that is 15ft above the ground. when he is 10 ft from the base of the light, 1) at what rate is the tip of his shadow moving? 2) at what rate is the length of his shadow changing? The answers are 1) -50/7...

could it be that rearranging the equation (v1)=(v2)+at yields a = delta v/t while rearranging d=(v1)t + 0.5at^2 d/t^2= (v1)/t^2 + 0.5a

Alright, this is a physics lab in which the motion of a glider on an airtrack is being used to calculate gravity. The lab asks us to find gravity in two ways: one-algebraically by using the fact that (v2)^2-(v1)^2=2ad and a=g sin theta where theta is the angle of the airtrack with the ground...

Homework Statement Why did we choose to linearize our data by plotting velocity versus time rather than by distance versus time-squared. Use d-v-a-t (distance=velocity*time+0.5*acceleartion*time-squared) equations to present a convincing answer. Homework Equations 1. d=vt+1/2at^2 2...

Thanks berkeman, I will definitely check this website out. And thanks for the insight that you have given me. It is insane how high schoolers have to start thinking about the complexities of life so early, but it is always good to have a place to throw out questions and get some different...

Out of curiosity, berkeman, how did you come up with the ideas for your out of school projects. I would definitely consider doing stuff like that. I am what most people call, a fiddler. I like to fiddler with stuff in my spare time. Examples: I built a tooth pick bridge in a vacuum to see if...

What are some of the opinion's floating around about double majors or dual degrees? Good, Bad, Horrible, let me know what you think ;)

I agree with Dark Knight as far as more EE are needed than physicists. I would also say that I think that the 10:1 ratio might even be fairly accurate, maybe a bit on the low side even. Is it wrong for me to conclude then that because more EE are needed that they have more security. I am...

Again Berkeman, I feel that my opinions on this subject are inferior as I am not qualified to give any more than my limited knowledge. I am just trying to figure out whether or not Physics or EE is a better choice. My knowledge is basic and is derived from my age (high school). Based on the...

I looked into doing the same thing that you are doing. I figured out that a physics/EE double major would require me to stay an additional year. There was something like a 40 hr. credit difference. Not saying that it can't be done, just pointing out that EE classes are pretty exclusive from...

Well Mr. Berkeman, You do have a compelling point; I believe myself to be wrong then on the issue of getting replaced. I guess that what I was trying to point out that because the market has plenty of EE, two things result: 1. harder to stand out from others in the field than physicists...

Yeah, unfortunately you haven't mentioned any new info to me. I do not qualify for financial aid. Apparently I am too rich to get aid and too poor to afford it. Bummer. Anyway, I am really quite interested in Auburn because they have a interesting situation. Many of their students have...
