Final answer:
The frequency of the vibrations on the tire tread pattern can be calculated using the formula: frequency = velocity / wavelength. In this case, the frequency will be 750 Hz.
Step-by-step explanation:
Physics - High School
The frequency of the vibrations can be calculated using the formula: frequency = velocity / wavelength. In this case, we need to convert the distance between crevices into wavelength. Since one crevice occurs every 2.00 cm, the wavelength would be twice this value, which is 4.00 cm. As the car moves at 30.0 m/s, we need to convert the wavelength to meters and then use the formula to find the frequency. Thus, the frequency of the vibrations will be 750 Hz.
