SUMMARY
The discussion focuses on the relationship between air resistance and car velocity, establishing that air resistance grows proportionally to the square of the velocity. Given that the air resistance is 0.18 kN at a velocity of 54 km/h, the equation for air resistance can be formulated as R = k * v², where R is air resistance, v is velocity, and k is the constant of proportionality. By solving for k using the provided values, users can calculate air resistance at different velocities, such as 90 km/h, and determine the velocity corresponding to an air resistance of 0.30 kN.
