How much energy is in a soccer ball that is moving at 3 m/s and has a mass of 2kg.
To calculate the energy of a moving object, we need to use the equation for kinetic energy:
Kinetic Energy = 0.5 * mass * velocity^2
In this case, the mass of the soccer ball is 2kg, and the velocity is 3 m/s.
Plugging these values into the equation:
Kinetic Energy = 0.5 * 2kg * (3 m/s)^2
Now, let's calculate it step-by-step:
Step 1: Square the velocity:
(3 m/s) ^ 2 = 9 m^2/s^2
Step 2: Multiply the squared velocity by the mass and the coefficient 0.5:
0.5 * 2kg * 9 m^2/s^2
Step 3: Finally, multiply the resulting value by the mass and the coefficient:
Kinetic Energy = 9 J
Therefore, the soccer ball has a kinetic energy of 9 joules (J) while moving at a speed of 3 m/s with a mass of 2kg.
