Answer:
The correct answer is : No.
Explanation:
If friction is zero, a vehicle cannot move on the road as friction is the force that enables the vehicle to gain traction and move forward. If there is no friction, the vehicle's wheels will not be able to grip the road and it will not be able to accelerate or maintain its speed. This is why friction is an essential factor to consider in vehicle dynamics.
However, in certain ideal situations, it may be assumed that the friction is zero for simplification purposes. For example, in the derivation of the expression for the banking angle of a road, the friction is ignored to isolate the effects of gravity and centripetal force. This is because the angle of the road's banking is designed to provide the necessary centripetal force to keep a vehicle moving on a curve at a certain speed without the need for excessive friction.
In real-world scenarios, friction cannot be completely eliminated, and therefore, it is always considered in vehicle dynamics calculations. Neglecting friction can lead to inaccurate results and can be dangerous when designing roads, vehicles, or any other systems that rely on motion and traction.
