Does the direction of friction change based upon where the force is coming from? My brother and I are discussing it... Specifically...if a car is operating under its own power vs. a car being towed The two scenarios are such... A car under its own power...the frictional force is static...

I got it. Thanks. Much much karma to you.

I get get the answer to be distance equals 0 because i use: vi to be 5 m/s vf to be -5m/s a to be -10 I plug those into the equations mentioned above. It seems to be the incorrect answer but doesn't it make sense? I must be missing fundamental here.
