% Inputs:
%     p_cart_x: Coordinate of Cart
%     param_plot: Struct varable for drawing Cart
%         l_equi    : Equilibrium of Length of Spring & Damper
%         l_w_c     : Width of Cart
%         l_h_c     : Height of Cart
%         l_hdl_s   : Lengths of Hundle parts of Spring
%         num_s     : Number of turn of Spring
%         l_box_d   : Width of Dashpot part of Damper
%         p_wg_org  : Reference position of Wall & Ground
% Oputput: Hundle of Plot
