If the system is released from rest ( = 0), what is the magnitude of the angular velocity of the bars when = 20 ?

If the system is released from rest (θ = 0◦), what is the magnitude of the angular

velocity of the bars when θ = 20◦

? Each bar has a mass of 8 kg and a length of 1 m. The

spring constant is k = 75 N/m, and the spring is unstretched when θ = 0◦
