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.
