Answer:
Force, F = 715.11 newton
Step-by-step explanation:
Given that,
Mass of the person, m = 65 kg
Acceleration of man during a running turn,

We need to find the magnitude of force experienced by the foot due to the ground. It can be calculated using second law of motion as :
F = ma

F = 325 Newton
Here, the weight of the person and this force force a right angle triangle.
The wight of the person, W = mg

So, the resultant for is,


So, the f force experienced by the foot due to the ground is 715.11 newtons. Hence, this is the required solution.
