The force of friction is given in the scenario:

Force = 500 Newton

and the mass of the runner  is 60 kg

To find the acceleration we need to use the relation between force, mass, and the acceleration of the object:

[tex]F=m\times a[/tex]

Where 'F' represents the force, 'm' represents the mass, and 'a' represents the acceleration.

Plugging the value of variables we get:

[tex]500=60\times a[/tex]

Solving for 'a' (acceleration) we get:

[tex]a= \frac{500}{60} =8.33[/tex] Newton/kilogram or meters/ second squared

So the acceleration of the runner is 8.33 meters/ second squared.
