2023SPp1q3 What is the air resistance when the speed is doubled?

This question is challenging to students as there are many information given. But it is actually quite straight forward when you save one thing at a time.

In this question, it is given that speed doubles, air resistance increases by four times. The actual relationship is speed is directly proportional to speed^2.

This question can be more challenging if this is given instead or that a random other speed is given. Watch the second part of the video to understand this deeper, especially for Pure Physics students.
