Answer

Explanation:

Step1: Recall the formula

The formula for gravitational - potential energy is $U = mgh$, where $m$ is the mass, $g$ is the acceleration due to gravity ($g = 9.8\ m/s^{2}$), and $h$ is the height.

Step2: Substitute the values

Given $m = 68\ kg$, $h=7.5\ m$, and $g = 9.8\ m/s^{2}$. Then $U=68\times9.8\times7.5$. First, $68\times9.8 = 666.4$. Then, $666.4\times7.5=4998\ J$.

Answer:

4998 J
