In this problem, we are required to apply Hooke's and graphical techniques to determine the spring constant.
Toy makers 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.
