MATLAB: How to animate multiple lines at the same time

animateanimatedlinecometMATLABmultiple lines

Hey, I have this code and have been using the comet function to animate each line. I want to animate all of the at the same time but have not been able to do so… Anybody have ideas?

% Initial Values

m1 = 1.04e-25;
m2 = 1.04e-26;
d = 0.1; %cm

v = 2e5; %(m/s)
B = 0.01; %Kg/(C)(s)
%Formulas
r= m*v/(B*q);%m



r1= m1*v/(B*q);
r2= m2*v/(B*q);
