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

00:05

brought to you by armadillos when startled armadillos can jump

00:09

several feet in the air So surprise parties are just

00:12

out of the question All right check out the following

00:16

chart right here The chart above represents the velocity of

00:19

a twenty kilogram armadillo as a function of time What

00:22

is the change in linear momentum along the interval from

00:25

six to twelve seconds and hear the potential answers Okay

00:31

well armadillos are pretty cool They're kind of like armored

00:34

rodents and yes some of them can get pretty big

00:36

so we shouldn't be too impressed with our twenty kilo

00:39

specimen here But we're not here to talk about zoology

00:41

so let's get into physics A change in linear momentum

00:44

is equal to the change in velocity and a constant

00:46

mass system Andy the armadillo and we give the name

00:50

isn't shedding mass here so that's the kind of system

00:54

we're dealing with change in momentum equals mass times the

00:57

change in velocity since andy here is slowing down by

01:01

two meters per second Change in momentum equals twenty kilograms

01:05

times two meters per second some quick multiplication and we'll

01:08

see that the correct answer here is be the change

01:11

in linear momentum is forty kilograms times meters per second

01:14

We just have to remember that a change in linear

01:16

momentum equals the change in velocity should also remember that

01:20

armadillos can carry leprosy So maybe that surprise party isn't 00:01:24.182 --> [endTime] such a good idea after all no
