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 spring and object are compressed by 0.061 meters, released from rest and subsequently oscillate back and forth with an angular frequency of 15.1 rad/s. What's the speed of the object at the instant when the spring is stretched by 0.046 meters relative to its unstrained length?
