Hooke's law describes a certain light spring of unstretched length 34.2 cm. When one end is attached to the top of a doorframe and a 6.75 kg object is hung from the other end, the length of the spring is 40.4 cm. (a) Find its spring constant. 1.066 kN/m (b) The load and the spring are taken down. Two people pull in opposite directions on the ends of the spring with a force of 199 N. Find the length of the spring in this situation. |0.37
