Question

applying technology to solve a problem
you are a biologist who is studying athletic performance. your lab equipment includes a wind machine, stopwatches, and computers. describe how you might use that technology to analyze this following problem:
how is a runners speed affected by wind?

Explanation:

Step1: Set up wind conditions

Use wind machine for headwind, tailwind, control.

Step2: Time the runs

Use stopwatches for each run of set distance.

Step3: Calculate speed

Apply \(v = \frac{d}{t}\) formula.

Step4: Input and analyze data

Use computer software for data input and analysis (graphs, stats).

Answer:

Use the wind machine to create different wind conditions (e.g., headwind, tailwind, no wind as a control). Have runners run a set distance (e.g., 100 meters) multiple times under each wind condition. Use stopwatches to time each run. Then, use the formula \(v=\frac{d}{t}\) (where \(v\) is speed, \(d\) is distance, and \(t\) is time) to calculate the speed for each run. Input the data (wind condition, time, calculated speed) into a computer. Use software (like spreadsheet software or statistical analysis software) to analyze the data. For example, create graphs (e.g., speed vs. wind condition) to visually see how wind affects runner's speed. Also, perform statistical tests (if applicable) to check for significant differences in speed across different wind conditions.
