Question: The 20-kg rod is released from rest when = 0. Determine its angular velocity when = 90. The spring has an unstretched length

The 20-kg rod is released from rest when θ = 0°. Determine its angular velocity when θ = 90°. The spring has an unstretched length of 0.5 m. A W 2m -2m- B 1 m k = 100 N/m

A W 2m -2m- B 1 m k = 100 N/m
