Governing equation of the Spring-Mass system is F1 k1 F2 m1 where k? and k2 is the stiffness of the spring (spring constant) and F1 and F2 is force applied to the mass mi and m2. k2 Create Matlab M-file to solve following problems. m2 (1) What is yi and y2 when ki 10 N/m, k2- 20 N/m, k3- 15 N/m, and F1-5 N, F2 3N? k3 (2) Plot y? and y2 when k2 continuously changes from 1N to 20N (3) Plot yi and y2 when both ki and k2 continuously changes from 1N to 20N (4) When ki 10 N/m, k2- 20 N/m, you want change the spring ks to make y1-2y2 What should be the value of k3? (5) What is the eigenvalues and vectors of the Spring matrix K? REMARK: In plot, use legend command to label your line
