Answer:

0.25 s

Explanation:

The angular velocity, ω, is related to the angular displacement, θ, by

[tex]\omega = \dfrac{\theta}{t}[/tex]

t is the time.

Making t subject of the formula,

[tex]t = \dfrac{\theta}{\omega}[/tex]

Substituting values in the question,

[tex]t = \dfrac{5}{20} = 0.25\text{ s}[/tex]
