Answer:
The kinetic energy of the object at a speed of 2 meters per second is 20 joules.
Explanation:
From the definition of the kinetic energy we get that kinetic energy is directly proportional to the square of the linear velocity. That is:
Where:
- Kinetic energy, measured in joules.
- Proportionality constant, measured in joules per square meter per square second.
- Speed, measured in meter per second.
Now we can determine the kinetic energy by using the following extrapolation:
If we know that , and , the kinetic energy is:
The kinetic energy of the object at a speed of 2 meters per second is 20 joules.
