Final answer:
When slowing for a turn, some traction is used to turn the vehicle, which is due to the force of friction between the tires and the road. This friction provides the necessary centripetal force to navigate the turn without sliding out. Traction and friction are integral to vehicle control, especially on curves and in varying driving conditions. Option d. lost forever.is correct.
Step-by-step explanation:
When you slow for a turn, some traction is utilized to decelerate the vehicle, while another part of the traction is used to initiate and maintain the turn. The traction that is used to slow the vehicle down is derived through the interaction between the tires and the road surface and is crucial for changing speed safely.
In physics terms, friction plays a significant role in this process. However, the answer to the question is that when slowing for a turn, some traction is c. used to turn. This is because turning the vehicle requires a sideways force, known as the centripetal force, which is provided by the friction between the tires and the road.
This friction is also responsible for preventing the car from sliding out of the turn, which supports the concept of the net external force on the vehicle equalling the horizontal centripetal force when turning.
To ensure the maximum safe speed at which a vehicle can turn on a curve without sliding, a combination of the correct speed and adequate friction between the tire and road surface is necessary.
This concept also ties in with the understanding that if a car takes a banked curve at less than the ideal speed, additional friction is needed to keep it from sliding. Moreover, various driving conditions, such as icy roads, demand different types of tires that create more friction to maintain safety and control.
Option d. lost forever.is correct.
