A ball is revolving horizontally in a circle of radius 1.8 m, and is held by a rigid, massless rod. The mass of the ball is 0.1 kg. The path of the ball has a constant linear speed of 27 m/s. What is the angular velocity of the orbit in rad/s?

Respuesta :

Answer:

 [tex]\omega=15 \ rad/s[/tex]

Explanation:

given,

radius of circle = 1.8 m

mass of the ball = 0.1 Kg

linear speed of the ball = 27 m/s

angular velocity of orbit = ?

 [tex]v =  r \omega[/tex]      

ω is the angular speed of the circle

 [tex]\omega=\dfrac{v}{r}[/tex]      

 [tex]\omega=\dfrac{27}{1.8}[/tex]        

 [tex]\omega=15 \ rad/s[/tex]              

the angular velocity of the orbit is [tex]\omega=15 \ rad/s[/tex]
