A light spring obeys Hooke's law. The spring's unstretched length is 33.0 cm. One end of the spring is attached to the top of a doorframe and a weight with mass 7.75 kg is hung from the other end. The final length of the spring is 45.5 cm.(a) Find its spring constant.
1. 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 of 150 N. Find the length of the spring in this situation.
