Toymakers have always been interested in springs for the entertainment value of the motion they produce. One well-known application is a baby bouncer, (Intro 1 figure) which consists of a harness seat for a toddler, attached to a spring. The entire contraption hooks onto the top of a doorway. The idea is for the baby to hang in the seat with his or her feet just touching the ground so that a good push up will get the baby bouncing, providing potentially hours of entertainment. The following chart depicts an experiment to determine the spring constant for a baby bouncer.

What is the spring constant k of the spring being tested for the baby bouncer?
Express your answer to two significant figures in newtons per meter.
k=______N/m
