initial momentum = final momentum
m×v + 2m×0 = (m+2m) × v'
mv = 3mv'
v' = mv/3m = v/3
Final velocity of combination is v/3
m×v + 2m×0 = (m+2m) × v'
mv = 3mv'
v' = mv/3m = v/3
Final velocity of combination is v/3
TPS:
are you in 9th class?
if yes, go and study this topic for a week, do the exercises and then come back so that you can see for yourself
because it's answer is written in my book and that is -2mv
you re in which class
9th
Simar, look, the answer can never be -2mv. Velocity can never be (mass×velocity). it will never be -2mv
And if it is really given in your book that the answer to this question is -2mv, then i sincerely request you to read a different book.
ok thanks
welcome
I am in 10

their velocity and momentum conserved conservation of momentum
