jisko iss question ka answer pata hai sirf vahi comment karo, agar koi altu faltu comment karega to main use report karungi​

Answer 1

Explanation:

M=30 V=48

m1=18 v1=0

m2=12 v2=?

MV=m2v2

30*48=12*v2

v2=120

Answer 2

Answer:

120m/sec

Explanation:

Here we can apply conservation of linear momentum

Initial momentum =30×48=1440Kgm/sec

Let speed of 12Kg mass be v m/sec

So final momentum = 12×v

=> 12v=1440

=> v=120m/sec.
