A British researcher developed a formula to determine walking or running speed based on hip height and stride length. The formula is s= 0.78l ^1.67/ h^1.17 where s is speed in meters per second l is stride length in meters
Oh, I see! So it's like a secret formula to unlock the mysteries of human locomotion? Probably the formula was developed by a physics-loving mad scientist sipping tea and solving the greatest riddles of walking and running. That's just so British! It sounds like this formula magically calculates speed based on the length of your strides and the height of your hips. Who knew math could be so hilarious? So, are you ready to put your hips and strides to the test?
To determine walking or running speed using the formula provided, you will need to know the values of hip height and stride length for a particular individual.
1. Measure the hip height: Start by measuring the distance from the ground to the surface of the hips (in meters).
2. Measure the stride length: To measure the stride length, have the individual walk or run a known distance (e.g. 10 meters) and count the number of strides taken. Divide the distance traveled by the number of strides to obtain the average stride length (in meters).
Once you have obtained the values for hip height (h) and stride length (l), follow these steps to calculate the speed (s):
1. Substitute the values of hip height (h) and stride length (l) into the formula:
s = 0.78l^1.67 / h^1.17
2. Calculate the stride length to the power of 1.67: Raise the stride length (l) to the power of 1.67.
3. Calculate the hip height to the power of 1.17: Raise the hip height (h) to the power of 1.17.
4. Divide the value obtained in Step 2 by the value obtained in Step 3.
5. Multiply the result in Step 4 by 0.78 to calculate the walking or running speed (s) in meters per second.
It is important to note that this formula provides an estimation and individual variations may exist. Additionally, there might be other factors that can affect walking or running speed, such as fitness level, terrain, and effort put in by the individual.
To determine the walking or running speed using the formula s = 0.78l^1.67 / h^1.17, follow these steps:
Step 1: Measure the stride length (l) in meters. This is the distance covered from one step to another.
Step 2: Measure the hip height (h) in meters. Hip height is the distance from the ground to the hips.
Step 3: Plug the values of stride length (l) and hip height (h) into the formula: s = 0.78l^1.67 / h^1.17
Step 4: Calculate the stride length raised to the power of 1.67.
Step 5: Calculate the hip height raised to the power of 1.17.
Step 6: Divide the value calculated in step 4 by the value calculated in step 5.
Step 7: Round the final result to the appropriate number of significant figures or decimal places.
Step 8: The resulting value will be the walking or running speed in meters per second (m/s) based on the given hip height and stride length.
