1. The problem statement, all variables and given/known data To set a speed record in measured (straight) distance d, a race car must be driven first in one direction (in time t1) and then in the opposite direction (in time t2). (a) To eliminate the effects of the wind and obtain the car's speed vc in a windless situation, should we find the average of d/t1 and d/t2 (method 1) or should we divide d by the average of t1 and t2? (b) What is the fractional difference in the two methods when a steady wind blows along the car's route and the ratio of the wind speed vw to the car's speed vc is 0.0240? 2. The attempt at a solution I've tried Part A, and got: Method 1: Vc = 1/2[d/t1 + d/t2] Method 2: Vc = 2d/(t1 + t2) Overall, this problem is irksome. I've spent the past 2 hours working on it, and my answers have become inconceivable. It's not even one of the problems I'm assigned to do, but I have an annoying tendency to finish whatever I completed, meaning if I wrote the problem down, I have to solve it. So to those who can help, much appreciation.
