Create an "xspeed" variable and an "xmax" variable. Set xmax to, say, 4. Then, do a script like this:

forever
set [xmax] to (4) 
if < key [right arrow v] presed >
 set [xvel v] to 0
 forever if < key [right arrow v] pressed >
  change x by (xvel)
  change [xvel v] by (1)
   if < <(xvel) > (xmax) > >
    set [xvel] to (xmax)

    set [xvel v] to (xmax)
 

Fixed your scripts.

Give this a try:

Create a variable called "Velocity" and another one called "LKP" and use this script:

when gf clicked
set [Velocity v] to [0]
forever
  if <key [left arrow v] pressed?>
    set [LKP v] to [1]
    change [Velocity v] by (-0.5)
  end
  if <key [right arrow v] pressed?>
    set [LKP v] to [2]
    change [Velocity v] by (0.5)
  end
  if <(Velocity) > (4)>
    set [Velocity v] to (4)
  end
  if <(Velocity) < (-4)>
    set [Velocity v] to (-4)
  end
  if <<<(LKP) = [1]> and <(Velocity) > (0)>> or <<(LKP) = [2]> and <(Velocity) < (0)>>>
    set [Velocity v] to [0]
  end
  set (Velocity) to ((Velocity) * (0.7))
  change x by (Velocity)
end

What is "LKP"?

  change x by (Velocity)
end
