Question

8 formula 1 point calculate the potential energy of a 62 kg person sitting on top of a 8 m tree. report your answer to 1 decimal place. your permitted error is ±0.1 j. do not put units into the answer field.

Explanation:

Step1: Identify the formula

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

Step2: Substitute the values

Given $m = 62\ kg$, $h = 8\ m$, and $g = 9.8\ m/s^{2}$. Substitute these values into the formula: $U=62\times9.8\times8$.

Step3: Calculate the result

$U = 62\times9.8\times8=62\times78.4 = 4860.8$.

Answer:

$4860.8$
