On Saturday, Ms Jenkins drives her pickup in the parking lot and does donuts while traveling a 22 m radius circle at 8.2 m/s. What is the static coefficient of friction between the tires and the pavement?

Final answer:

The minimum coefficient of static friction cannot be determined without knowing the specific mass of the car.

Step-by-step explanation:

In order to calculate the minimum coefficient of static friction between the tires and the pavement, we need to find the centripetal force exerted on the car. The formula for centripetal force is Fc = mv²/r, where m is the mass of the car, v is the velocity of the car, and r is the radius of the circular curve.

Given the radius of 22 m and the velocity of 8.2 m/s, we can calculate the centripetal force. However, the specific mass of the car is not provided in the question, so we cannot determine the exact value of the coefficient of static friction.

Therefore, the minimum coefficient of static friction cannot be determined without knowing the specific mass of the car.
