If your runnin at full speed for an average human, and lept over a 10 foot brook would you make it?

Unless you are a mutantI don't think you would make it. I'm 5'8" and most people are 6'7" or less. It's bsically impossible to do. :)

This seems a bit too trivial for this site but I'll bite anyways. An average speed for a human would be around 8 mph, so running would probably be around 12 mph. The longest long jump ever is 26 feet, but the average is 7' 3" to 7' 6.5", which is quite far away from the 10 ft brook. Therefore nope!

(a)

(b)0.033

Explanation:

(a)

Force F=mg where m is mass and g is acceleration due to gravity whose value is taken as

However, for this case, the maximum force is 8 times the weight of runner hence F=8mg

Assume Young's modulus for tendon is

Young's modulus is given by

and and substituting F with 8mg we obtain

Where E is young's modulus, l is stretched length and \triangle l is change in length

Substituting m as 70 kg, g as , l as 15cm=0.15 m, E as and A as

(b)

Strain, and the fraction of tendon’s length is the ratio of change in length to the stretched length

The fraction of tendon, f is given by

. Substituting with 0.005m and l with 0.15m we obtain

Therefore, fraction of the tendon’s length is 0.033
