Answer:

[tex]K=63J[/tex]

Explanation:

Hello,

In this case, the kinetic energy is defined as:

[tex]K=\frac{1}{2}mv^2[/tex]

Thus, since the mass is 14 kg and the velocity is 3 m/s we compute the resulting kinetic energy as shown below:

[tex]K=\frac{1}{2} *14kg*(3m/s)^2=63kg*m^2/s^2[/tex]

Nonetheless, based on the definition of Joules (N*m) as the major unit of energy, we shall understand that kg*m²/s² also equals Joules, for that reason the result is:

[tex]K=63J[/tex]

Best regards.
