Figure out horizontal force necessary to move an object

AI Thread Summary
To determine the horizontal force needed to move an object with a coefficient of kinetic friction of zero, it is essential to overcome the maximum static friction, which is also likely zero in this scenario. Once the object is in motion, if kinetic friction is zero, no additional force is required to maintain that motion. An initial impulse is necessary to start the movement, but thereafter, no force is needed to keep it moving. This understanding clarifies the relationship between static and kinetic friction in this context. The discussion concludes with the realization that the problem was solved independently.

how do you figure out horizontal force necessary to move an object if the coefficient of kinetic friction is zero?

It must be just big enough to over come the maxium static friction, then it will drop to the kinetic friction value of zero. But if kinetic friction is zero, it would probably be true that static friction is zero as well. But if you are moving, and you have zero kinetic friction, it takes zero force to keep it moving. You just need to give it an impulse to get it moving in the first place.
 
thx that helped...i actually figured it out on my own...

Thread 'Gauss' law seems to imply instantaneous electric field'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'Highway: Deriving speed from Doppler shift'

I passed a motorcycle on the highway going the opposite direction. I know I was doing 125/km/h. I estimated that the frequency of his motor dropped by an entire octave, so that's a doubling of the wavelength. My intuition is telling me that's extremely unlikely. I can't actually calculate how fast he was going with just that information, can I? It seems to me, I have to know the absolute frequency of one of those tones, either shifted up or down or unshifted, yes? I tried to mimic the...
