3. Find the transfer function X2(s)/F(s) for the system shown in figure below. fy are the coefficients of the viscous fiction for the corresponding blocks. Ki and K2 are the spring constants. Force f(t) is applied on block of mass M1, x1(t) and x2(t) are the direction of movements of the corresponding blocks. 0000 f(1) x₁(1) X2(1) K3 M₂ 0000 [$ 0000A 0000 fv₂
