I made some code about FreeFall from Physics.
I compleded coding with numbers clearly.
The problem is that i do not know how to visualize this code properly.
I just can make linear line to visualize my code.
I want to make a moving box following my parabolic.
Also, i want to make small airplane following the horizontal line.
I tried to use SET command but i do not know how it works.
Thanks.

It's hard to understand exactly what you're looking for. It might help to upload a hand-drawn picture of what you want to create and upload some sample data for us to work with. This should solve the airplane bit.
Also a heads-up: some folks on this forum bristle at "send-it-to-me" requests because the forum is supposed to be for everyone to learn from. It's a subtle difference, but sending code directly by email feels less like community learning and more like free consulting.

function userinput
% Making a Target
clf
TargetCenter=floor(rand(1)*100); TargetHigh=TargetCenter+10;
plot([TargetCenter TargetHigh], [0 0],'m') axis([-10 110 0 100])
hold on
% UserInput
while 1 % velocity v=input('Velocity(m/s): ');
%Height
H=50;
% g
g=9.81;
% time
t=sqrt(2*H/g);
% time interval
dt=0.3;
%
R0=v*t;
for x=0:dt:R0
%want to be a moving box!
y=-9.8/(2*v.^2)*x.^2+50;
plot(x,y);
% want to be in the shape of an airplane
y=50;
plot(x,y);
drawnow;
end
if R0>=TargetCenter & R0<=TargetHigh
fprintf('Success!\n\n');
break;
end
end

this is my code. I tried to fix 4 points around the CenterPoints of each two linear lines. Then I tried to move the box and airplane by using SET command. But it was not working.
I tried as many things as possible, but failed. hope you can give me an idea.
