A wheel starts from rest and rotates with constant angular acceleration to reach an angular speed of 11.9 rad/s in 3.10 s. (a) Find the magnitude of the angular acceleration of the wheel.

Respuesta :

Answer:

The value is  [tex]\alpha = 3.84 \ rad/s^2[/tex]

Explanation:

From the question we are told that

    The constant angular speed is  [tex]w = 11.9 \ rad/s[/tex]

     The time taken is  [tex]t = 3.10 \ s[/tex]

Generally the magnitude of the angular acceleration is  mathematically represented as  

          [tex]\alpha = \frac{w}{t}[/tex]

=>     [tex]\alpha = \frac{11.9}{ 3.10 }[/tex]

=>     [tex]\alpha = 3.84 \ rad/s^2[/tex]
