Just a slight improvement

def velocity(c, m, t, dt, vi)
   vel = []

   (t/dt + 1).times do
     vel << vi
     vi +=  ( G - c/m*v) * dt
   end

   vel
end

You could also do

def velocity(c, m, t, dt, vi)
   (t/dt + 1).times do
     yield vi
     vi +=  ( G - c/m*v) * dt
   end
end

and use it with a block.

Kind regards
