Hi
This is Ritika
I franckly say I am not sure this answer is right or wrong because it has been a year ago when I use to practice this type of questions.
But according to me
Force =mass *acceleration
F =m*dv/dt
And as he fires n bullet so
F=n*m*dv/dt
According to Newton third law every action has equal and opposite reaction.
So reaction force per sec on the man will be mndv/dt .
Please do tell me my answer is right or wrong if wrong what is correct answer.
Thank you
