A 132 kg car and a 2150 kg pickup truck approach a curve on a frictionless road with a radius of 235 m. What is the coefficient of static friction between the tires of the car and the road?

(Note: The answer cannot be expressed in degrees; please provide the coefficient as a unitless value.)

Answer :

Final answer:

Given the context, it is impossible to calculate the coefficient of static friction as the conditions specified create a paradox. In the real world, which experiences friction, a vehicle's tires and the roadway surface interact, generating the necessary centripetal force for moving in a curve. In a frictionless scenario, this curving would be theoretically impossible as per Newton's First Law.

Explanation:

The question appears to contain a miscommunication. The given information does not provide the necessary details to calculate the coefficient of static friction, and also seems to misunderstand its nature. Essentially, static friction prevents an object from starting to move. It is calculated as μN, where μ is the coefficient of static friction and N is the normal force between the two objects involved, often a tire and the road in vehicle scenarios.

In general, the centripetal force caused by a vehicle moving in a curve is the result of static friction between its tires and the road. In a frictionless scenario like in the question, it needs to be stated that technically, a vehicle could not maintain a curve as there would be no force to counteract the momentum of the vehicle trying to continue in a straight line (Newton's First Law).
