mia places her backpack, which has a mass of 4 kg on a shelf that is 2 meters high. how much gravitational potential energy does the backpack on the shelf?

Question

Accepted Answer

# Explanation:
## Step1: Recall the formula for gravitational potential energy
The formula for gravitational potential energy is $U = mgh$, where $m$ is the mass, $g$ is the acceleration due to gravity ($g = 9.8\space m/s^{2}$), and $h$ is the height.
## Step2: Substitute the given values into the formula
Given $m = 4\space kg$, $h=2\space m$, and $g = 9.8\space m/s^{2}$.
$$
\begin{align*}
U&=(4\space kg)\times(9.8\space m/s^{2})\times(2\space m)\
&=4\times9.8\times2\space J\
& = 78.4\space J
\end{align*}
$$

# Answer:
$78.4\space J$
