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

00:05

brought to you by newton meters which are unfortunately not

00:08

three foot long cookies figure consider a spinning gear rotating

00:13

clockwise this way A torque of ten newton meters is

00:17

exerted clockwise for three seconds What's the change in angular

00:23

momenta mme and hear the potential answers All right all

00:28

right well it sure feels like we've been working on

00:30

a lot of these mo mentum questions lately in between

00:32

watching silly cat videos on the internet Of course i

00:35

can has shmoop all right but this one's a little

00:38

different here we're dealing with angular momenta mme or what

00:42

high level physicists call momentum of attorney things it's a

00:46

spell to find the change in angular momentum We need

00:49

the product of the average torque exerted would write it

00:53

And the period of time the torque was applied Seasonal

00:56

play by tip kind In this case that means we

01:00

take our ten newton meters and we multiply that by

01:03

three seconds giving us a solution of thirty kilogram meters

01:07

per second So option d is the correct answer That's

01:09

it i'm to pause for a silly cat video and

01:12

to take some time to wonder what kind of oven 00:01:14.223 --> [endTime] can handle a three foot long cookie
