There is a question, it says that if wheel of radius 14 inches is rotating at 0 .25 radians per second.
00:06
So, radius of the wheel is 14 inches and its angular velocity omega is 0 .25 radians per second and i have to round the answers to two decimal places.
00:23
What is the linear speed? so, linear speed of the vehicle is v equal to r omega.
00:30
So, i will be plugging in over here 14 inches and 0 .25.
00:37
So, this will be 3 .50 inches per second.
00:44
This is 3 .50 inches per second is the linear speed.
00:49
Now i have to find what is the angular speed in degrees.
00:53
Angular speed in degrees.
00:54
So, angular speed is being already mentioned over here.
00:58
Omega equal to 0 .25 radians per second.
01:02
So, we know that 180 degrees equal to pi radians.
01:10
So, 1 radian will be 180 by pi degrees.
01:16
So, 0 .25 radian will be 180 by pi into 0 .25 degree.
01:25
So, let us plug in over here.
01:28
It will be 180 by pi into 0 .25 degree per second.
01:38
I will be using calculator.
01:40
This will become 180 into 0 .25 divided by pi.
01:46
So, this is 14 .3239 degrees per second...
