Brain Teaser - Riding against the wind
Here is a short brain teaser that you can cogitate on next time you are out on a bicycle...
Question 1: Solve the puzzle "Riding against the wind" given here Sam Lloyd puzzle - courtesy of Math is Fun Question 2: Solve the puzzle again, but now with some additional assumptions included - No acceleration or deceleration - No up or down grade slope - Riders power (watts) is constant in both directions and weight with bicycle is 100kg - Wind is constant speed with air density = 1.28 kg/m^3 - Coeff of rolling resistance = 0.004 - Coeff of wind * Frontal area = 0.4 m^2 - Drivetrain efficiency = 95% Question 3: What else can you determine about the rider, bicycle and/or wind? Enjoy and remember your units... |
