## Answers ( )

Answer:Angular frequency is 20 rad/s.

Explanation:Given that,

A block is attached to an oscillating spring. The function below shows its position (cm) vs. time (s) is given by :

…..(1)

The general equation of oscillating particle is given by :

…….(2)

Compare equation (1) and (2) we get :

So, the angular frequency of the oscillation is 20 rad/s.
