Write a function ball that calculates the trajectory of a volleyball in 2 dimensions numerically using the Euler method. The initial values x(0) und v(0) should be passed to the function. It should return a matrix for the place x(t) and velocity v(t), respectively, that contain the values for all time instances in the columns (rows contain the values for the two dimensions). Stop the calculation when the ball hits the floor. The trajectory should be plotted and the values of time of flight and maximum range should be calculated.

Hi Munther

Check out this code:

clear x,y,theta,u,n,g,h,u0;
x(1) = 0;
y(1) = 0; g = 9.81; h = 5; u0 = 80;
theta = pi / 6;
u(1) = u0*sin(theta);
for n=2:10
x(n) = x(n - 1) + v0*cos(theta)* h;
u(n) = u(n - 1) - h*g;
y(n) = y(n-1) + h*u(n-1);
end
plot(x,y);
