Answer

Explanation:

Step1: Recall kinetic - energy formula

The formula for kinetic energy is $K = \frac{1}{2}mv^{2}$, where $m$ is the mass and $v$ is the velocity.

Step2: Substitute given values

Given $m = 50.0\ kg$ and $v = 18\ m/s$. Substitute into the formula: $K=\frac{1}{2}\times50.0\times(18)^{2}$. First, calculate $(18)^{2}=324$. Then, $\frac{1}{2}\times50.0 = 25.0$. Finally, $K=25.0\times324 = 8100\ J$.

Answer:

C. 8,100 J
