Consider the following spring experiment. One end of a spring is connected to a stationary object while the other end is connected to a scale. Which of the following methods will most accurately approximate the total amount of work required to stretch the spring 10 cm?

  1. Stretch the spring 10 cm and record the force measured by the scale.
  2. Stretch the spring 5 cm, record the result, stretch the spring an additional 5 cm and record the second result. Average the two recorded results.
  3. Stretch the spring 5 cm, record the result, stretch the spring an additional 5 cm and record the second result. Sum the two recorded results.
  4. Stretch the spring 5 cm, record the result, stretch the spring an additional 5 cm and record the second result. Multiply the two recorded results.
  5. This approximation is not possible.
