Neco 2022 Physics Question 12
Practice objective / multiple choice question 12 from the 2022 Neco Physics examination.
The force-extension graph for a spring is given by the points (0\,cm,\,0\,N), (2\,cm,\,5\,N), (4\,cm,\,12\,N), (6\,cm,\,21\,N) and (8\,cm,\,32\,N). The first two points lie in the linear elastic region.\n\n(a) Determine the spring constant \(k\) from the linear region (in N·m\(^{-1}\)).\n\n(b) Using the trapezoidal rule between successive points, calculate the work done in stretching the spring from 0\,cm to 8\,cm. Give your answer in joules to two decimal places.
