The frequency of the radio station is

For radio waves (which are electromagnetic waves), the relationship between frequency f and wavelength

is

where c is the speed of light. Substituting the frequency of the radio station, we find the wavelength:
Answer: 2.74
Explanation:
We can solve this problem using the stopping distance formula:

Where:
is the distance traveled by the car before it stops
is the car's initial velocity
is the coefficient of friction between the road and the tires
is the acceleration due gravity
Isolating
:

Solving:

This is the coefficient of friction
1 astronomical unit = 149597870700m
Enrico should divide distance in meters with this number.
