Hello everyone, I recently encountered that dreaded moment when walking where you get a face full of an seemingly invisible spider web. It got me thinking about why these webs are so difficult for humans to distinguish; unless of course we see them at the correct angle. Do they somehow bend...

Yes i see now, thank you.

oh! it's a kinematics question? so vf^2=vi^2*2ax so v final = 0 because it comes to a rest v initial = (2 x 10^3)^2 x = .15m solving for a we get a = 1.33 x 10^7 which is the correct answer, thank you. Why do we not into account the electric field in this type of question? is there...

A proton initially moves left to right along the x-axis at a speed of 2 x 10^3 m/s. It moves into an electric field, which points in the negative x direction, and travels a distance of 0.15m before coming to rest. What acceleration magnitude does the proton experience? equations E = kq/r^2...
