Friction and cars (or any traveling thing)

[shredder666]

lets take the situation of a traveling toy car with 1kg of mass...
If the maximum force of friction between the car and the road is, let's say, 1N, then is it possible for the car to have >1m/s^2 acceleration?

Is there an incline?

 

[shredder666]

no just a flat surface

Hey
I think that is possible
because you said that
m=1 Kg
max friction force=1N
okay, see when the car will move it's equation will be
x comonent
F(applied force)-f(friction force)=ma
if you raise your applied force you will get acceleration greater than 1m/s2

the only force propelling a car is friction between tires and the road, which will determine the maximum acceleration (and deceleration) if you want to neglect drag; trying to apply any higher force will result in slipping and actually less propelling force because the tires will go from static to dynamic friction.
The answer to the original post is no, it not possible (unless you carry a rocket engine in the trunk)
