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 athlete is 70.0 kilograms. The velocity is 12 meters per second.
Substitute the values into the formula.

Solve the exponent.
- (12 m/s)² = (12 m/s)(12 m/s) = 144 m²/s²

Multiply the numbers together.


Convert the units. 1 kilogram meter squared per second squared is equal to 1 Joule, so our answer is equal to 5,040 Joules.

The athlete has 5,040 Joules of kinetic energy.
