syms T t0 D V Sv Sy y0 v0 Lamday LamdavT t
T = t0 + D/V; % We Define T as the final time at wich two objects will have the same distance
MatrixA = [Sv+T T*(Sv*T/2); -T^2/2 Sy-T^3/6];
DeterminantA = (Sy + T^3/3)*(Sv + T) - T^4/4
initials =[y0; v0];
Lamda = [Lamday; LamdavT]; 
Lamda = (MatrixA * initials)/DeterminantA
vt = v0 - t*(LamdavT + T*Lamday) + (T.^2)/2 * Lamday % we define v(t) as the velocity at any time t
yt = y0 + t*v0 - (t.^2)/2 *(LamdavT + T*Lamday) + (t.^3)/6 * Lamday
LamdavT = Sv*vt;
Lamday = Sy*yt;
t = 1:9;
y0=0; v0=0; t0=0; D =3; V = 2; 
y1 = y0 + t*v0 -(t.^2)/2 *(1.5 + T * 0.5) + (t.^3)/6 * 0.5;
plot(t,y1)

Best Answer

plot(t,eval(y1))
