What is the maximum walking speed of an adult man whose legs are each 0.90 m long?
3.0m/s
Use the equation v=sqrt(rg)
plug in 9.81 m/s^2 and the radius which is .9 meters and you will get approximately 2.97 which you can round up to 3 m/s
To determine the maximum walking speed of an adult man with legs measuring 0.90 m each, we need to consider a few factors. Firstly, we can use the concept of stride length to estimate walking speed.
Stride length is the distance covered in one step while walking. On average, a person's stride length is about 0.4 to 0.6 times their leg length. Let's assume the average value of 0.5 times the leg length for this calculation.
So, the stride length for an adult man with 0.90 m long legs would be:
Stride length = 0.5 * Leg length
= 0.5 * 0.90 m
= 0.45 m
Now, to calculate walking speed, we need to consider the time it takes for each stride. Typically, a person takes about 0.5 to 0.7 seconds per stride while walking at a comfortable pace. Let's use an average value of 0.6 seconds per stride.
To calculate the maximum walking speed, we need to multiply the stride length by the number of strides taken per second:
Maximum walking speed = Stride length * Strides per second
Strides per second = 1 / Time per stride = 1 / 0.6 = 1.667 strides per second
Therefore:
Maximum walking speed = 0.45 m * 1.667 strides per second
= 0.74985 m/s
Therefore, the estimated maximum walking speed for an adult man with 0.90 m long legs would be approximately 0.75 m/s.
