first frame the question properly
 
if it says that 1/n of initial velocity is lost then n such plancks would be required
 
but if it says that 1/n of its velocity is lost then the answer would be infinite no of planks would be required
 
 
think over this if you dont get the logic please post another question with your doubt
 
hope this was helpfull
