A horizontal spring is lying on a frictionless surface. One end of the spring is attaches to a wall while the other end is connected to a movable object. The spring and object are compressed by $0\mathrm{.}055$ m $,$ released from rest, and subsequently oscillate back and forth with an angular frequency of $17\mathrm{.}5ra\frac{d}{s}.$ What is the speed of the object at the instant when the spring is stretched by $0\mathrm{.}033$ m relative to its unstrained length?
