We have equation of motion

Here u = 0, v= 237 m/s, S = 0.66 m;
Hence acceleration of bullet,
Force of action = Force of reaction


Hope the answer and explanation helps you. All the best wishes for your studies ?

Momentum and Impulse 2. Your favorite rifle (22 caliber) has a mass of 3.0 kg, a 40 cm long barrel and weigh 2.6 g (a) Before you fire the rifle, how much momentum does the bullet have? (Not a trick question, I hope) (b) Before firing, what is the momentum of the rifle? (c) The bullet is fired with a velocity of 370 m/s. What is the bullet's momentum? (d) With what velocity does the rifle move backwards (Le. recoil)?...

Question 7 is related to the force vs mass graph that is
provided and the first section of the excel sheet. Question 3 has
to do with the force bs acceleration graph and second section of
the excel sheet. The first two files are showing the equations that
are supposed to be used to find these answers. Any help would be
greatly appreciated.
