[QUOTE="greg_rack, post: 6400556, member: 672853"] [B]Homework Statement:[/B] The resistance to the motion of a car is directly proportional to the square of the speed of the car. The car increases its speed by 20%. What is the percentage increase in the resistance to the motion of the car? [B]Relevant Equations:[/B] Percentage increase; So, I simply used the percentage increase formula for the resistance force, but what I come up with is a 9.5% increase, as opposed to the 44% it should be... Here's my procedure: [ATTACH type="full"]270390[/ATTACH] [/QUOTE]
