Ah. you added the distances traveled. Remember when dealing with velocities you're dealing with vectors, and the vectors are in completely opposite directions here--the two must be subtracted.

Yes, my bad. Should've said displacement, but the calculations are in fact calculating the displacement, not the distance.

Well for 1... you want to take the distant traveled north. That's straightforward, just don't get stuck on units. Remember, Distance = Speed * Time Then measure the distanced traveled south, subtract that to have the total distance traveled. You now will have a distance, and you know the time...

sorry to pester, but any ideas? thanks.

Homework Statement Imagine there are two parallel current-carrying coils, radius R, perpendicular to and centered on the x-axis, with centers at 0.5D and -0.5D. Both carry a current I in the same direction (clockwise). We would like to adjust D so that the magnetic field created by the coils...
