1. how much potential energy does a monkey up in a tree have? the monkey has a mass of approximately 11 kg and is 14 meters high.

define variables
pe =
m = 11kg
g = 9.8m/s²
h = 14m
write equation and show work
pe=11×9.8×14 =
answer w/ units
1509.2j

1. a city sets up a hydroelectric dam and they need about 25,000,000 joules of energy produced every second. what is the mass of water that is necessary to create that kind of energy, if the dam is 42 meters high?

Explanation:

Step1: Identify the formula for gravitational - potential energy

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

Step2: Calculate the potential energy for the monkey

Given $m = 11\ kg$, $g=9.8\ m/s^{2}$, and $h = 14\ m$. Substitute these values into the formula:
$PE=mgh=(11\ kg)\times(9.8\ m/s^{2})\times(14\ m)$
$PE = 11\times9.8\times14\ J$
$PE=1509.2\ J$

Answer:

$1509.2\ J$
