P.3) A thoughtful king once decided to update the drawbridge of his castle by attaching the middle of the drawbridge to the castle wall via a single linear spring with an unstretched length of 6 m. The drawbridge is 12 m long, has a rotational inertia of about O of 21,600 kg-m², and has a mass of 450 kg. The king has decreed that the spring constant shall be 690 N/m. What's the velocity with which the end of the drawbridge will strike the ground if it's released from a nearly vertical position? 不 6 m -6 m→ ww k 6 m
