Introduction
In the world of physics, understanding the kinetic energy of an object is crucial in determining its mass, velocity, and other properties.

We will use the formula for kinetic energy, $KE = \frac{1}{2} mv^2$, to solve a problem involving a soccer ball.
What is Kinetic Energy?
Kinetic energy is the energy an object possesses due to its motion. It is a measure of the energy an object has when it is in motion. The kinetic energy of an object depends on its mass and velocity. The more massive an object is and the faster it moves, the more kinetic energy it possesses.
The Formula for Kinetic Energy
The formula for kinetic energy is given by $KE = \frac{1}{2} mv^2$, where $KE$ is the kinetic energy, $m$ is the mass of the object, and $v$ is its velocity. This formula shows that the kinetic energy of an object is directly proportional to its mass and the square of its velocity.
Solving the Problem
Now, let's solve the problem given in the introduction. A soccer ball is traveling at a velocity of $50 , \text{m/s}$. The kinetic energy of the ball is $500 , \text{J}$. We need to find the mass of the soccer ball.
Using the formula for kinetic energy, we can write:
Simplifying the equation, we get:
Multiplying both sides by 2, we get:
Dividing both sides by 2500, we get:
Simplifying the fraction, we get:
Therefore, the mass of the soccer ball is $0.4 , \text{kg}$.
