An object that weighs 19.0 N is placed on a horizontal, frictionless table in front of a spring that has a constant k (see the figure below). When the spring is compressed and released, the object shoots off the table and is caught on the end of a 2.30-m-long massless string.

When the spring is compressed and released, the object shoots off the table and is caught on the end of a 2.30-m-long massless string. The object then moves in a circular path. The string doesn’t break unless the spring is compressed more than 1.00 m. The maximum tension the string can sustain is 200 N.
What is the value of the spring constant? (Ignore the fact that it would be odd for a string to be standing straight up as shown.) (Express your answer to three significant figures.)
