answer would be appreciated

The figure below illustrates a two-degree- of-freedom system. Mass m = 10 kg is located at the end of a clamped beam with a mass of m = 10 kg, a Flexural rigidity of - EI = 4000 Nm, and a length of L = 2 m. Mass m is connected to mass m = 20 kg using two springs, k1 = 4000 N/m and k2 = 8000 N/m, as shown in the figure. Determine the second mode shape vector? (-4.24) (-5.56) (-3.75) (-2.25) ( +1)
