Final answer:
In Physics at the High School level, calculating the number of revolutions made by a tire involves the formula relating distance traveled to the circumference of the tire. The student must convert distance to meters, then divide by the product of 2π and the tire's radius in meters.
Step-by-step explanation:
The subject of the question is Physics, and it appears to be at a High School level, focusing on rotational motion and angular velocity. To find the number of revolutions the tires make, we would use the relationship between distance traveled, the radius of the tire, and the angle of rotation.
To solve for the number of revolutions, given that an automobile with 0.260 m radius tires travels 80,000 km, we use the formula:
Number of revolutions = Distance traveled / (2 π × Radius of tire)
First, convert 80,000 km to meters to have consistent units: 80,000 km = 80,000,000 meters. Then, calculate:
Number of revolutions = 80,000,000 m / (2 π × 0.260 m)
After carrying out the calculation, we will get the total number of tire revolutions over the 80,000 km distance traveled.
