Please help me! I need answer asaap if you can...

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.
