1. The problem statement, all variables and given/known data The force felt on an auto due to its movement through still air varies approx. as the square of the car's speed. (the force is also known as air resistance) assume the force varies exactly as the square of the speed. around town at 30mi/hr a car experiences an air resistance force of 100lbs. what size force would you expect the car to face while traveling at 65mi/hr? 2. Relevant equations car travels at 65mi/hr at 30 mi/hr its air resistance force is 100 lbs. 3. The attempt at a solution ive been looking at this problem for the last hour, and i dont know what good the weight will help me with. ive tried conversion but it gets me nowhere. i dont want the answer, i just want to know how should i approach the problem, and how do i start!
