Question

what is the potential energy of a 3 kg cat sitting on top of a 2 m wall? a 6 j b 58.8 j c 288.1 j

Explanation:

Step1: Identify 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 $m = 3\ kg$, $h=2\ m$, and $g = 9.8\ m/s^{2}$. Substitute into the formula: $U=3\times9.8\times2$.

Step3: Calculate the result

$U = 3\times9.8\times2=58.8\ J$.

Answer:

B. 58.8 J
