A horizontal spring is lying on a frictionless surface. One end of the spring is attached to a wall while the other end is connected to a movable object. The object and spring are compressed by 0.083 meter, released from rest, and subsequently oscillate back and forth with an angular frequency of 13.0 rad/s. Determine the speed of the object at the instant when the spring is stretched by 0.049 meter relative to its unstrained length?
