Answer:
angular acceleration = 0.54 rad/s/s
Explanation:
Initial angular speed of the wheel is ZERO as it starts from rest
final angular speed is given as
[tex]\omega_f = 19 rad/s[/tex]
[tex]\Delta t = 35 s[/tex]
now we know that angular acceleration is rate of change in angular speed
[tex]\alpha = \frac{\Delta \omega}{\Delta t}[/tex]
here we have
[tex]\alpha = \frac{19 - 0}{35}[/tex]
[tex]\alpha = 0.54 rad/s^2[/tex]
