A horizontal spring is lying on a friction less surface. One end of the spring is attaches to a wall as the other end is connected to a movable object. The spring and object are compressed by 0.056 m, released from rest, and subsequently oscillate back and forth with an angular frequency of 16.8 rad/s. What is the speed of the object at the immediate when the spring is stretched by0.035 m relative to its unstrained length?A horizontal spring is lying on a frictionless surface.
