Hi, 

The question: 

Create a table of the droplet´s range as a funstion of the initial velcity for v0=0.2..4 m/s in steps of 0.2 m/s, each with starting angle of 36 degree. What range of Reynolds numbers does this correspond to? Plot the result.   

I get the result for one of the v values, but struggling to get values for all the v-values. 

F_D:=proc(v::list) #force/mass
local k,vx,vy;
vx:=v[1];
vy:=v[2];
k:=-evalf(3*Pi*mu*d/m);        #common constant, calculated only one time
[k*vx,k*vy];                           #returns a vektor
end proc;

 
Euler:=proc(vo::list,h)             #using the Euler method to solve the equations
local vx,vy, F;
F:=F_D(vo);
vx:=vo[1]+h*F[1];
vy:=vo[2]+h*(F[2]-g);
[vx,vy];
end proc;
