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 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.
Homework Statement
A particle moving at 5 m/s reverses its direction in 1s to move at 5 m/s in the opposite direction. If is acceleration is constant, what distance does it travel?
