how can i subplot 4 separate graphs for machine's velocity

A machine velocity while traveling on a particular road = 70*exp(-t/M) t=0:0.5:10

M is the mass of the Machine. Machine1 is 100kg Machine2 is 150kg Machine3 is 200kg how can i subplot the velocity vs time graph of each machine so that i get the velocity-time graph of each respective machine?

below is what ive tried. Welcome other alternative suggestions!

V0=70 for m=100:50:200 l=length(m) for i=1:l t=linspace(0,10,l) V(i)=70.*exp(-t(i)./M(i)); subplot(3,1,i) plot(t,V)

    end
end

Here is one alternate:

V = 70;
machine = [100 150 200 250];
t=0:0.5:10;
for i = 1:numel(machine)
    road = V*exp(-t/machine(i));
    subplot(2,2,i), plot(t, road), title(strcat('weight:', num2str(machine(i))))
end
