What is the kinetic energy of a soccer ball which has a mass of 4 kg and is kicked at a velocity of 10 m/s?
what is 1/2 * 4 *10^2 ?
To find the kinetic energy of an object, you can use the formula:
Kinetic Energy = 1/2 * mass * velocity^2
Given that the mass of the soccer ball is 4 kg and the velocity is 10 m/s, we can substitute these values into the formula:
Kinetic Energy = 1/2 * 4 kg * (10 m/s)^2
First, calculate the square of the velocity:
Velocity^2 = (10 m/s)^2 = 100 m^2/s^2
Now, substitute the mass and squared velocity into the formula:
Kinetic Energy = 1/2 * 4 kg * 100 m^2/s^2
Now, calculate the product of mass and squared velocity:
Kinetic Energy = 1/2 * 4 kg * 100 m^2/s^2 = 200 kg m^2/s^2
Therefore, the kinetic energy of the soccer ball is 200 kg m^2/s^2.
