Thank you We sneak and here's your shmoop du jour

00:05

Brought to you by peaches They're delicious but would it

00:08

kill him to shave every once in a while All

00:11

right Margarets planning peach trees in her back yard She

00:14

drops large peach pits into small holes one at a

00:17

time Each pit has a mass of one kilogram and

00:21

she dropped them in from a height A zero point

00:24

five meters what's the potential energy of the pit At

00:28

the instant it falls from her hand And here the

00:32

potential answers way go day huh Well these are some

00:37

really big peach pit But that's how we get politic

00:40

peaches All right At the instant the peach pit is

00:43

released from margaret's hands It's not moving it will But

00:47

we're talking the very very incident it's released So all

00:51

of the energy involved is potential energy not kinetic All

00:59

right potential energy equals mass times gravity times height So

01:04

all we have to do is plug in the Numbers

01:06

1 kilogram times 10 meters per second squared times point

01:11

five meters gives us an answer of five jewels So

01:14

option is the correct answer To be sure to memorize

01:17

These equations They'll come in handy a test time Another

01:20

thing to remember Be nice to margaret Maybe she'll take

01:23

us a peach pie if those trees whose work out
