Using MATLAB command solve the following questions: 21) The following data is obtained from an experiment aimed at measuring the spring constant of a given constant. Different masses m are hung from the spring and the corresponding deflections & of the spring from its upstretched configuration are measured. m(g) 5.00 10.00 20.00 50.00 100.00 8(mm) 15.5 33.07 53.39 140.24 301.03 Fit a straight line through the data and display the spring constant 'K' on the figure.
