Answer :
When a flywheel, initially at rest, has a constant angular acceleration. After 9 s, the flywheel has rotated 450 rad. Its angular acceleration is: 11.1m/[tex]s^{2}[/tex].
The temporal rate at which the angular velocity changes is known as angular acceleration. The angular velocity can be determined by performing an integral on this, which is typically a derivative. The angular acceleration in this issue could, however, be a significant change in the angular velocity divided by the corresponding time interval due to the fact that it is constant.
Using the equation, we get acceleration of flywheel as:
θ = ωot + 1/2α[tex]t^{2}[/tex]
and putting the values:
α = 11.1m/[tex]s^{2}[/tex]
Therefore, when a flywheel, initially at rest, has a constant angular acceleration. After 9 s, the flywheel has rotated 450 rad. Its angular acceleration is: 11.1m/[tex]s^{2}[/tex].
