$\boxed {\boxed {\sf 299.568 \ Joules }}$

Explanation:

Kinetic energy can be found using the following formula:

$E_k=\frac{1}{2}mv^2$

where m is the mass and v is the velocity.

The mass of the person is 60 kilograms and the velocity is 3.16 meters per second

$m= 60 \ kg \\v= 3.16 \ m/s$

Substitute the values into the formula.

$E_k=\frac{1}{2} (60 \ kg) *(3.16 \ m/s)^2$

First, evaluate the exponent.

(3.16 m/s)²= (3.16 m/s) * (3.16 m/s) = 9.9856 m²/s²

$E_k=\frac{1}{2}(60 \ kg ) (9.9856 \ m^2/s^2)$

Multiply 60 kg by 9.9856 m²/s²

$E_k=\frac{1}{2} (599.136 \ kg*m^2/s^2)$

Multiply 599.136 kg*m²/s² by 1/2, or divide by 2.

$E_k=299.568 \ kg*m^2/s^2$

1 kg*m²/s² is equal to 1 Joule Therefore, our answer of 299.568 kg*m²/s² is equal to 299.568 Joules.

$E_k= 299.568 \ J$

The running person has a kinetic energy of 299.568 Joules.
