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.
- m= 4.7 kg
- v= 7 m/s
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.
