What is the kinetic energy of the F-22 Raptor Jet Fighter weighing approximately 100,000 kg and traveling at a speed of 600 meters per second?

Understand the Problem

The question is asking us to calculate the kinetic energy of the F-22 Raptor Jet Fighter given its weight and speed. To solve this, we will use the formula for kinetic energy, which is KE = 0.5 * m * v^2, where m is mass and v is velocity.

Answer

The kinetic energy of the F-22 Raptor can be calculated using the formula $KE = 0.5 \cdot m \cdot v^2$, where mass is derived from weight divided by $g$.

Steps to Solve

Convert Weight to Mass

The weight of the jet is given, and we need to convert it into mass. Weight (W) is related to mass (m) through the equation:

$$ W = m \cdot g $$

Where $g$ (acceleration due to gravity) is approximately $9.81 , \text{m/s}^2$.

Thus, the mass can be calculated as:

$$ m = \frac{W}{g} $$

Calculate the Kinetic Energy

Using the mass calculated in the previous step, we can now calculate the kinetic energy (KE) using the formula:

$$ KE = 0.5 \cdot m \cdot v^2 $$

Where $v$ is the velocity.

Substituting Values

Substitute the mass $m$ and the speed $v$ into the kinetic energy formula:

$$ KE = 0.5 \cdot \left( \frac{W}{g} \right) \cdot v^2 $$

This will give us the kinetic energy in joules.

The final kinetic energy can be calculated using the values of weight and speed plugged into the formula.
