Question

the total momentum before collision is always equal to total momentum after collision... true or false? ​

Answer 1

Answer:

TRUE

Explanation:

DUE TO THE LAW OF CONSERVATION OF MOMENNTUM

Answer 2

Answer:

False

Explanation:

Since no external force acts on the system during the collision, the total momentum of system before and after the collision remains the same.

Hence the sum of momenta of the objects before the collision is same as the sum of momenta after the collision.

Clearly in option C, this happens.

Hence correct answer is option C.
