Question

net extemal force is zero on a system the total momentum is constant." This is called Law
of conservation of momentum. This law can be proven using the second law of motion. As
according to it
F-
If, FO then
-=0
or AP=0
or total momentum before collision = total momentum after collision.
Answer the following questions based on above paragraph
(i) An object of mass 10 kg moves with velocity of 5 m/s. The momentum is
(a) 2 units
(b) 50 units
(c) 5 units
(d) 15 units​

Answer 1

Answer:

50 units is your answer ...mark.

Answer 2

The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
