Conservation of momentum
Pinitial=Pfinal
MaVa+MbVb=MtotalVfinal
(5.5)(9)+(5.5)(5)=(5.5+5.5)V
49.5+27.5=11V
77/11=V
7m/s=V
The answer to that question is c. tamod
Answer: The net force acting on an object is the sum of all the force acting on it, and the net force of an object is zero. I f the forces acting on it tend to cancel each other. For example you are sit in a chair, the earth's gravity is pulling you down, but the chair is pushing you up with an equal amount of force.
There is my answer from my notebook .I hope its good :)
A substance which allows the un-interrupted flow of electric current is called an electric conductor
