What is the kinetic energy of a 25 kg dog that is running at a speed of 7.9 m/s (about 18 mi/h)? answer in___J

Sagot :

In order to calculate the kinetic energy, we can use the formula below:

[tex]KE=\frac{mv^2}{2}[/tex]

Where KE is the kinetic energy (in J), m is the mass (in kg) and v is the velocity (in m/s).

So, using m = 25 kg and v = 7.9 m/s, we have:

[tex]\begin{gathered} KE=\frac{25\cdot7.9^2}{2}\\ \\ KE=780.125\text{ J} \end{gathered}[/tex]
