Answer with Step-by-step explanation:
We are given that
Radius of circle=r
Total distance traveled =s
Time=t
Central angle=[tex]\theta[/tex] rad
We know that
Linear speed,v=[tex]\frac{distance}{time}[/tex]
Using the formula
Therefore, v=[tex]\frac{s}{t}[/tex]
Angular speed,[tex]\omega=\frac{Angular\;displacement}{time}[/tex]
By using the formula
[tex]\omega=\frac{\theta}{t}[/tex] rad/s
The linear speed and angular speed is required.
The linear speed is [tex]v=\dfrac{\theta r}{t}[/tex]
The angular speed is [tex]\omega=\dfrac{\theta}{t}[/tex]
[tex]\theta[/tex] = Angle in radians
[tex]t[/tex] = Time
[tex]r[/tex] = Radius
Linear Velocity is given by
[tex]v=\dfrac{\text{Distance}}{\text{Time}}[/tex]
Here the distance will be the arc length
[tex]\text{Distance}=\theta r[/tex]
So,
[tex]v=\dfrac{\theta r}{t}[/tex]
Linear velocity can also be written as
[tex]v=\dfrac{\theta}{t}r\\\Rightarrow v=\omega r[/tex]
So, [tex]\omega=\dfrac{\theta}{t}[/tex]
