1. ### Distance From a Velocity-Time Graph

Velocity=distance/ time. multiply by the time stamp at whatever point you are on on the graph.
2. ### Can someone explain polarization states to me in really simple terms?

and what difference does it make if it is negative? it says its direction can be counter clockwise or clockwise on the wiki, is negative pi/4 a counterclockwise direction then
3. ### Can someone explain polarization states to me in really simple terms?

ok so if i had an equation like E=iE0sin(wt-kz)+ jE0sin(wt-kz-pi/4), i should be dividing one by the other to get the ratio of x to y and that will tell me if it is circular, elliptical or linearly polarized? so in that case it varies by a pi/4 component which would make it, elliptical? is there...
4. ### Finding final velocity.

Didnt you just find the final velocity? they asked for acceleration, so you should be solving for that since you have the time. you can find out the acceleration
5. ### Can someone explain polarization states to me in really simple terms?

Let's say I have an equation E=iE0cos(kz-wt)-jE0cos(kz-wt), how do I look at this and know, this is linearly polarized? or what if it changes and the kz is negative? or its a sin function with with (wt-kz-pi/4) in it. I just don't understand what this equation is supposed to be telling me and...
