Final answer:
The frequency of vibrations for a tire with a tread pattern of a crevice every 2.00 cm, with the car moving at 30.0 m/s, is 1500 Hz, which represents 1500 vibrations per second.
Step-by-step explanation:
The question pertains to the frequency of vibrations generated by the tire's tread pattern as the car moves. To calculate the frequency, we need to consider the speed of the car and the distance between the treads. Given that the car is traveling at 30.0 m/s and there is a crevice every 2.00 cm (or 0.02 m), we can calculate the frequency by dividing the speed of the car by the distance between crevices.
Frequency Calculation
Frequency (f) = Speed of the car (v) / Distance between crevices (d)
f = 30.0 m/s / 0.02 m
f = 1500 Hz
Therefore, the frequency of vibrations is 1500 Hz, meaning the treads make 1500 vibrations per second as the car moves at 30.0 m/s.
