Calculate the kinetic energy of a 3-kg dog that runs at a speed of 4 m/s
KE = 0.5M*V^2 Joules.
To calculate the kinetic energy of the dog, you can use the formula:
Kinetic Energy = (1/2) * mass * velocity^2
Given:
Mass (m) = 3 kg
Velocity (v) = 4 m/s
Substituting the values into the formula:
Kinetic Energy = (1/2) * 3 kg * (4 m/s)^2
First, let's square the velocity:
Velocity^2 = 4 m/s * 4 m/s = 16 m^2/s^2
Now, let's substitute the values back into the formula:
Kinetic Energy = (1/2) * 3 kg * 16 m^2/s^2
Simplifying the equation:
Kinetic Energy = 24 kg m^2/s^2
The kinetic energy of the 3-kg dog running at a speed of 4 m/s is 24 joules (J).
To calculate the kinetic energy of the dog, we can use the formula:
Kinetic Energy (KE) = 1/2 * mass * velocity^2.
In this case, the mass of the dog is 3 kg, and the speed is 4 m/s. Plugging these values into the formula, we get:
KE = 1/2 * 3 kg * (4 m/s)^2
Now, let's do the calculations step by step:
KE = 1/2 * 3 kg * (16 m^2/s^2)
First, we square the velocity:
KE = 1/2 * 3 kg * 16 m^2/s^2
Next, we multiply the mass and the squared velocity:
KE = 1/2 * 3 kg * 16 m^2/s^2
We get:
KE = 24 kg m^2/s^2
Therefore, the kinetic energy of the dog is 24 Joules (J).
