Explanation:
Explanation:
It is given that,
Mass of the runner, m = 70 kg
Length of the tendon, l = 15 cm = 0.15 m
Area of cross section, 
Part A,
Let the runner's Achilles tendon stretch if the force on it is 8.0 times his weight, F = 8 mg
Young's modulus for tendon is, 
The formula of the Young modulus is given by :



Part B,
The fraction of the tendon's length does this correspond is given by :


Hence, this is the required solution.
