Hooke's law describes a certain light spring of unstressed length 38.0 centimeter. When one end is attached to the top of a door frame and a 6.80 kilogram object is hung from the other end, the length of the spring is 45.50 centimeter.

(a) Find what is its spring constant.

kN/m

(b) The load and the spring are taken down. Two people pull in opposite directions on the ends of the spring, each with a force of180 Newton. Estimate the length of the spring in this situation.
