A 0.988 kg sphere is compressing and stretching a spring as it moves up and down relative to its relaxed position(spring not stretched or compressed at all). When in its relaxed position, the sphere is at 1.95 meters above the floor. If the sphere is released from rest at 12.0 cm above the relaxed position, what is the sphere's speed when it has stretched the spring a distance of 29.4 cm below its relaxed position? (Spring k = 20.0 N/m)
