The Air Resistance of a car grows proportional to the square of the velocity. On a certain car is the air resistance 0,18kN when the velocity is 54km/h.(adsbygoogle = window.adsbygoogle || []).push({});

So the problem is ..

What is the air resistance when the velocity is 90 km/h?

How high is the velocity when the air resistance is 0,30kN?

I don't understand how to do this please help me...
