A light spring obeys Hooke's law. The spring's unstretched length is 32.0 cm. One end of the spring is attached to the top of a doorframe and a weight with mass 8.25 kg is hung from the other end. The final length of the spring is 44.5 cm. Find its spring constant (in N/m). If the weight and the spring are taken down and two people pull in opposite directions on the ends of the spring, each with a force of 150 N. Find the length (in m) of the spring in this situation. From the answer in b), what would be the length (in m) of the spring if it was now attached to the vertical portion of the doorframe and stretched horizontally by a single person exerting a force of 150 N?

Question

A light spring obeys Hooke's law. The spring's unstretched length is 32.0 cm. One end of the spring is attached to the top of a doorframe and a weight with mass 8.25 kg is hung from the other end. The final length of the spring is 44.5 cm.

  1. Find its spring constant (in N/m).
  2. If the weight and the spring are taken down and two people pull in opposite directions on the ends of the spring, each with a force of 150 N. Find the length (in m) of the spring in this situation.
  3. From the answer in b), what would be the length (in m) of the spring if it was now attached to the vertical portion of the doorframe and stretched horizontally by a single person exerting a force of 150 N?
