Mam, you work so hard making these one shot videos which are really really effective for learning and clearing concepts. And you are intelligent too because you teach 4 subjects so effectively without wasting our time, and in various languages (I have seen one of your bengali videos last year probably). And until you yourself understand the concept very clear, you can't teach it to someone else like so easily, it shows your intelligence in all way. God bless you. May you and your family always stay healthy and happy. Lastly, I am blessed to find a teacher like you who makes complex things so easy. THANK YOU VERY VERY MUCH MAM.

Because retarding f is acting opp to the direction of car ...so a will be opposite to the direction of car.
