A-more than bullet
B-less than bullet
C-same as bullet
plzz ans me as soon as possible

Answer 1

hey here is ur answer

it will be less than bullet

Answer 2

Answer:

according to conservation of momentum

momentum of gun-momentum of bullet as momentum-mass x

velocity as mass of bullet of is less than mass of gun therefore velocity of bullet is more than velocity of gun as

K.E-1/2 x m x v x v -1/2 x

momentum of gun velocity of bullet

therefore K.E OF BULLET IS MORE THAN OF K.E OF GUN
