A) State and prove with the help of a neat labeled diagrams the law of conservation of momentum
b) A gun of mass 5k g fires a bullet of mass 20 g with a speed of 100 m/s. Find
the recoil velocity of the gun. pls ive exam right now

Explanation:

                         GUN                                                                    BULLET

mass, m  = 5 kg                                                    mass, m = 20 g = 0.02 kg

initial velocity, u = 0                                              u = 0

final velocity, v = ?                                                 v = 100 m/s

v of the gun = m of the bullet × v of the bullet / m of the gun

= 0.02 × 100 / 5

= 2/5

= 0.4 m/s

Hope this helps

plz mark as brainlliest
