I said that because there wasn't an angle being given.

64x^2+7=5y-5 Take the log of both sides now. log64x^2+7=log5y-5 (4x2+7)log6=log5y-5 From here, isolate for one of the variables and substitute it into the original equation. Solve for the other once that is done.

Well I'm presuming the particle is experiencing horizontal projectile motion.To find the original velocity I would use dx=vx+1/2a(t)2, where x are the horizontal problems given in the question, such as the particle landing 2 m away horizontally, time can be used in both x and y component...

Homework Statement A child goes down a playground slide with an acceleration of 1.32 {m/s^2}. Find the coefficient of kinetic friction between the child and the slide if the slide is inclined at an angle of 35.0 deg below the horizontal. Homework Equations Fnet=ma Fg=mg Ff=uFn I...

Oh. Yeah I see that now thanks.

Homework Statement A turtle is moving with constant acceleration along a straight ditch. He starts his stopwatch as he passes a fence post and notes that it takes him 10s to reach a pine tree 10m further along the ditch. As he passes the pine tree, his speed is 1.2m/s. How far was he from the...

For #2, sec^2 will equal 1/cos^2, and tan^2 will equal sin^2/cos^2. If you have learned the Pythagorean Identity (sin^2+cos^2=1) you can isolate cos^2 and solve the left side, which will leave you with 1/1-sin^2. Solving the right side, tan^2 will equal sin^2/cos^2, and you can make 1 equal to...

Assume the equator is 0, and the max/min is 4500. This is your amplitude. You can find your period by using period=2pi/k, which would equate to: period= 360/45 period=8 (I believe your working in radians?) I might be wrong about the period, but it's pretty easy to go on from there. To do...

Do you have a right side to any of these equations? Or do you just have to get the equation to the simplest terms?

I don't think lambda was suppose to use in the original equation, was it? I forgot to add that part in my original question.

I think I might've worded my question wrong; I'm trying to prove the formula itself, I don't need to find the wavelength; unless that is what I am suppose to do?

Homework Statement This is my first post, so it might not be that great... Anyways, I need help deriving the formula. This formula is pertaining to the doppler effect, and more specifically, to find the frequency of a sound made from an object moving toward/away from you. f2= f1(v/v-vs) or...
