Unfortunately for Sebastian Sobieszek it is easy to retrieve the question body from Google cache (the two attached images can't be recovered this easily):
Simulation of ball bouncing the wall
Hello,
I am a beginner in the Matlab and I need some help.
I need to write a Matlab program that calculates the coefficient of restitution (k) for the given heights: h and h' values and value of v1' (the velocity of ball after hitting the wall). The program is also to show a simulation of the movement of the mass m1, which bounces once from the wall (the wall does not need to be shown in the simulation). The data is presented in the picture.
Thank you in advance for your help.
I can only simulate the pendulum motion in the program like this:
function pendulum
% l=20;
% g=9.81;
[t,teta]=ode45(@equation2,[0:0.1:10],[0,3]);
x=20*cos(teta);
y=sqrt(20^2-x.^2);
for i=1:100
plot([0,x(i)],[0,-y(i)],x(i),-y(i),'.r','MarkerSize',90);
axis([-20,20,-50,0])
pause(0.2)
end
function [dteta] = equation2(t,teta)
dteta=[teta(2);-9.81/20*sin(teta(1))];

See my attached bouncing ball demo. Obviously it's not meant to turn in as-is as the answer to your homework problem, but it might give you ideas.
