Answer 1

Answer:

Hii, dear don't cry i will let you know.

Explanation:

yes, by using the theorem from newton's third law of motion we know that in every action there is equal and opposite reaction.so here exists the recoil velocity. and from second law of motion that is law of conservation of momentum;

                   m1u1 +m2u2 = m1v1 m2v2

                                                               so by applying this formula your answer got correct.(9m/s).

as you have have asked for how it came so i have given the direct answer. you didnt asked for solution because you got it right!

ok so mark me as brainliest  .
