Thank you very much for your help!

Well if that equation I wrote is correct, then the sum of the forces changes, does it not? So while the projectile is going up it is: F=ma=-mg-kv Then when it comes back down (After Y_max) it would be: F=ma=-mg+kvSo what I am asking is, would I have to integrate those two functions separately...

Yeah, I understand what you mean, I think I over-analyzed the problem trying to over-complicate things, but integration superseded. So if I find a function of y, through this integration and such, that will be the function of y for the entire trajectory, correct? I am getting paranoid. Thanks...

I feel like this does not necessarily fit the format of a homework problem perse, but I am not sure where else to ask, but— I was doing a thought experiment of a trajectory with air resistance (Air-resistance being proportional to the velocity with some constant), and was thinking to solve it...

Oh, the reason I did not show my work, is because I believed that my whole concept was incorrect...I am allowed to assume this as a very long Solenoid? One second, let me get my work real quick. Alright, so I have the equation... B=mu_0*n*I*1/L and I find the magnetic field to be .01653 T...

Yup, you were right, I had to switch them...yet, I am still clueless as to why... But thank you for your help!

Ah, so the magnetic flux for the second surface is just the negative of the first surface? Yet, if that is the case...I still cannot obtain the correct answer for part (a). This is exactly what I typed in the answer box. cos(theta)*B*pi*R^2 And I looked at the preview of the answer..and...

Homework Statement A solenoid 2.50 cm in diameter and 26.0 cm long has 285 turns and carries 12.0 A. (a) Calculate the flux through the surface of a disk of radius 5.00 cm that is positioned perpendicular to and centered on the axis of the solenoid, as in Figure P30.36a. (b) Figure P30.36b...

My apology for that. Well, for part (a) I have tried my answer, yet, it is still wrong, and yes I have checked to make sure it was typed in correctly. For part (b) I believe it only wants the flux for the surface of two, so it is not closed without surface one, because zero was the incorrect...

Homework Statement Symbolic question: Consider the hemispherical closed surface in Figure P30.34. The hemisphere is in a uniform magnetic field that makes an angle θ with the vertical. (a) Calculate the magnetic flux through the flat surface (S1), using pi for π, theta for θ, B, and R as...
