Answer:
250 J
Explanation:
The kinetic energy can be calculated as:
[tex]K=\frac{1}{2}m\cdot v^2[/tex]Where m is the mass and v is the velocity. So, replacing m by 5 kg and v by 10.0 m/s, we get:
[tex]\begin{gathered} K=\frac{1}{2}(5)(10^2) \\ K=\frac{1}{2}(5)(100) \\ K=\frac{1}{2}(500) \\ K=250\text{ J} \end{gathered}[/tex]Therefore, the answer is 250 J
