Hi, everyone, good day.
first scenario will be:
let say, there are two cars, they share the same features except one, the mass of two cars are different (the mass of wheel, however, is the same). Now, if the two cars are accelerated to the same speed and then the engine is turned off, they will slide for some distance and then come to stop.
my question is, which car can slide further? and what theory explains the answer? (preferably, please use equation to explain)
originally, i am thinking of the lighter car can slide farther because the friction force act on it is lesser (smaller normal force), but i recalled that the body with higher mass has higher inertia, which maybe allows the heavier car to slide further.
second scenario will be:
two cars, they share the same features, including the total mass of the car. now, the thing that is different will be the mass of wheel of the cars. one car uses heavier wheel and the other lighter. the geometry of the wheels are exactly the same, just the mass is different (different material). Now, if the two cars are accelerated to the same speed and then the engine is turned off, they will slide for some distance and then come to stop.
In this case, which car can slide further? and what theory explains the answer?
can anyone clarify this for me? this has been bugging me for few days. thanks a lot!
