Question

potential energy = m g h. a flower pot has a mass of 2.5 kg and sits on a balcony 30 meters above the ground. how much potential energy does the flower pot have? pe = 2.5kg 9.8m/s² 30m =

Explanation:

Step1: Identify the formula

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

Step2: Substitute the values

Given $m = 2.5kg$, $g = 9.8m/s^{2}$, and $h = 30m$. Substitute these values into the formula: $PE=2.5\times9.8\times30$.

Step3: Calculate the result

$2.5\times9.8 = 24.5$, then $24.5\times30=735J$.

Answer:

$735J$
