A flywheel with a diameter of 10 centimeters, so i'm going to go ahead and write that down.
00:05
Diameter is 10 centimeters, which tells me about radius is 5 centimeters.
00:09
And i'm doing that because we always use the radius.
00:12
Is rotating at a rate of radiance per second.
00:16
How many radians per second? nine radians per second.
00:25
So our angular velocity is nine radians per second.
00:31
So what is the linear speed of a point on its rim in centimeters per minute? so we're going to know the linear velocity in centimeters per minute.
00:41
Well, we have our formula, v equals r omega.
00:45
That's why i went ahead and got r because i knew we were going to need it.
00:48
So that's going to be five centimeters times by angular velocity, which is nine radians per second...
