A horizontal spring is lying on a frictionless surface. One end of the spring is attached to a wall whle the other end is connected toa movable object. The spring and object are compressed by0.074 m, released from rest, and subsequently oscillate back and forth with an angular frequency of11.6 rad/s. What is the speed of the object at the instant when the spring is stretched by 0.041 m relative to its unstrained length?____________ m/s
