I am trying to generate multiple lines on a graph corresponding to velocities and launch angles. heres my basic code but how I do get it to loop with a single velocity but multiple launch angles?

thetaList=[0, .17453293 .52359878 .78539816 1.04719755 1.57079633];
for i = 1:length(thetaList)
  theta=thetaList(i);
end
hold on  
g= 9.81;
v0=[5]
tf=2.*v0.*sin(theta)/g;
t=0:0.01:tf;
x=v0*cos(theta)*t;
y=v0*sin(theta).*t - 0.5*g*t.^2;
plot(x,y)
