Answer:

Explanation:
Kinetic energy is the energy an object possesses due to motion. It is calculated with the following formula.

The mass of the object is 4.7 kilograms. The velocity of the object is 7 meters per second.
Substitute the values into the formula.

Solve the exponent.
- (7 m/s)²= 7 m/s * 7 m/s = 49 m²/s²

Multiply the numbers together.


Convert the units. 1 kilogram square meter per square second is equal to 1 Joule.

The object has <u>115.15 Joules</u> of kinetic energy.

Free energy is a thermodynamic potential that can be used to calculate the maximum reversible work that can be performed by a thermodynamic system at a constant temperature and pressure. It is fulfilled that if the energy change is less than zero it will mean that the relationship will proceed towards the product, while if the relationship is greater than zero the reaction will proceed towards the reactant. Therefore the correct option is D.
<em>The free energy change of a reaction can determine the reaction direction</em>
