How to plot a linear equation with a final condition

I want to plot the following:

V(t) = V0 * (1-t/ts);

Where V0 is my initial velocity, my time range is t = [t0 ts] and

V(ts)= 0;

I know I have to use a for loop, but don't know how to call the initial function into the loop or how to include the final condition.

V0 = [10 20 30 40 50];
Vel = @(t,V,ts) V0*(1-t/ts)
for j = 1:length(V0)
    
    figure (2)
    line(V0,Vel)
end

Any suggestions?

V(ts) = 0 does not add any new information V0 * (1-t/ts) -> V0 * (1 - ts/ts) -> V0 * (1 - 1) -> 0 . Therefore you did not need to be told V(ts) = 0 as it happens anyhow.

Hints:

1) If you have a row vector A which is 1 x M, and a column vector B which is N x 1, then

B * A

will be N x M in size.

2) plot() of something that is N x M in size will give you M lines on the screen, each containing N points.

ts=10;%not sure what ts should be
t=0:.1:ts;
V0 = [10 20 30 40 50];
hold on;
for k=1:length(V0)
    v=V0(k)*(1-t/ts);
    plot(t,v);
end

We do not encourage giving complete answers to homework problems. (When someone "has to" use a for loop, then you can tell that it is homework.)
