Answer:

Step-by-step explanation:
Kinetic energy is the energy an object possesses due to motion. It is calculated using the following formula:

The mass of the person is 70 kilograms and they are moving at a speed of 5 meters per second.
Substitute these values into the formula.

Solve the exponent.
- (5 m/s)² = 5 m/s * 5 m/s = 25 m²/s²

Multiply the numbers in parentheses.

Multiply by 1/2 or divide by 2.

Convert the units. 1 kilogram meter squared per second squared is equal to 1 Joule. So, our answer of 875 kg*m²/s² is equal to 875 Joules.

The person has 875 Joules of kinetic energy.
