How to plot a "goal" into my plot?

This is only to do something cool in the plot but I am plotting the trajectory of a soccer ball and I thought it would be cool to plot a "goal" (a rectangle) into the figure since I have a green surface that looks like a field already.

My code is the following:

%% Constants 
t = linspace(0, 10, 1000);
m = 0.4; %mass (kg)
g = 9.8; %gravitational accel. (m/s.^2)
b = 0.44; %drag coefficient
w_1 = 1.5; %Angular Velocity
w_2 = 1; %Angular Velocity
w_3 = 0.5; %Angular Velocity

%% w_1
x_t_1 = (2349.*m)./(100.*b) - (2349.*m.*exp(-(b.*t)./m))./(100.*b);
y_t_1 = (g.*m.*t.*w_1)./(b.^2 + w_1.^2) - (171.*b.^2.*m.*w_1)./(20.*(b.^4 + 2.*b.^2.*w_1.^2 + w_1.^4)) - (171.*m.*w_1.^3)./(20.*(b.^4 + 2.*b.^2.*w_1.^2 + w_1.^4)) - (2.*b.*g.*m.^2.*w_1)./(b.^4 + 2.*b.^2.*w_1.^2 + w_1.^4) + (171.*b.^3.*m.*exp(-(b.*t)./m).*sin((t.*w_1)./m))./(20.*(b.^4 + 2.*b.^2.*w_1.^2 + w_1.^4)) + (171.*m.*w_1.^3.*exp(-(b.*t)./m).*cos((t.*w_1)./m))./(20.*(b.^4 + 2.*b.^2.*w_1.^2 + w_1.^4)) + (171.*b.^2.*m.*w_1.*exp(-(b.*t)./m).*cos((t.*w_1)./m))./(20.*(b.^4 + 2.*b.^2.*w_1.^2 + w_1.^4)) + (171.*b.*m.*w_1.^2.*exp(-(b.*t)./m).*sin((t.*w_1)./m))./(20.*(b.^4 + 2.*b.^2.*w_1.^2 + w_1.^4)) + (b.^2.*g.*m.^2.*exp(-(b.*t)./m).*sin((t.*w_1)./m))./(b.^4 + 2.*b.^2.*w_1.^2 + w_1.^4) - (g.*m.^2.*w_1.^2.*exp(-(b.*t)./m).*sin((t.*w_1)./m))./(b.^4 + 2.*b.^2.*w_1.^2 + w_1.^4) + (2.*b.*g.*m.^2.*w_1.*exp(-(b.*t)./m).*cos((t.*w_1)./m))./(b.^4 + 2.*b.^2.*w_1.^2 + w_1.^4);

I'm not sure if a piecewise plot might be the way to go to get a rectangle at z=0, y=[-2 2], x=20 ?

Thanks for the help in advanced!

From what I read that is for a 2D plot. I'm hoping to put it in my 3D plot. Thanks!
