A slender 6.2-kg rod can rotate in a vertical plane about a pivot at B. A spring of constant k = 290 N/m and of unstretched length 150 mm is attached to the rod as shown. Knowing that the rod is released from rest in the position shown ( pos(1) ). The rod has rotated through 90°. The work done by spring is the 600 mm B 120 mm 350 mm
