What loops do I use?

I have an already created code below.

If I had to use loops in order to produce the same output (as the original code), what loops would I need to use and how? What would the code look like?

T=0:0.01:20;
V0=100;
G=9.8;
theta=pi/4;
HT=T*V0*cos(theta);
plot(T,HT);
title('horizontal path');
xlabel('time(s)');
ylabel('distance(m)');
%%
T=0:0.01:20;
V0=100;
G=9.8;
theta=pi/4;
VT=(T*V0*sin(theta))-((1/2)*G*T.^2);
plot(T,VT);
title('vertical path');
xlabel('time(s)');
ylabel('distance(m)');
