This is what i have done to find the difference between a ball thrown with different starting angle, and then ploted they into the same plot.

restart; Digits:=20: with(plots):

C_0:=0.4: d:=0.0002: mu:=1.8*10^(-5): rho:=1.2: g:= 9.81:
rho_v:=1000.0: m:=evalf((4/3)*Pi*rho_v*(d/2)^3):   


F_D:=proc(v::list)                 
local k,vx,vy; 
vx:=v[1]; 
vy:=v[2]; 

I have now been stck in a few days on a task that should be done in maple. I'm pretty new to maple so hope some of you could help me a bit. The task is to create a table of a ball that is thrown, when the starting speed should be from 0.2 to 4, and each step should be at 0.2. Afther that the table need to be plotted. I have used euler method to sett the functions up and the functions is a vector. Any one know what comands i should be using?
