Q9: The 0.75-kg particle is attached to the light slender rod OA which pivots freely about a horizontal axis through point O. The system is released from rest while in the position 0 = 0° where the spring is unstretched. If the particle is observed to stop momentarily in the position 0 = 50° , determine: 1. The spring constant k. 2. For your computed value of k, what is the particle speed v at the position 0 = 25° ?
