Question

i need this ans urgently
A 60 g bullet fired from a 5 kg gun with a speed of 500 m/s.find the recoil velocity of the gun?

Answer 1

as there will be action reaction force ,recoil velocity will be -6 m/s

Answer 2

No external is acting on gun bullet system hence initial and final momentum will be conserved.so
M(bi)V(bi)+M(gi )V(gi)=M(bf)V(bf)+M(gf)V(gf)
Where b=bullet
G=gun
i=initial f=final
Put and get answer.
