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

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
