Question

In case of collision of objects in two dimensions which statement is true after the collision?

A- the horizontal momentum is not conserved

B- the vertical momentum is not conserved

C- the horizontal momentum and the vertical momentum are both conserved

D- the horizontal momentum and the vertical momentum are not conserved

Thank you in advance!

Answer 1

In case of collision of objects in two dimensions, the statement that is true after the collision is :
C. The horizontal momentum and the vertical momentum are both conserved
That mean that the Collision is elastic, and occurs above an horizontal plates

hope this helps

Answer 2

The correct answer to the question is : C) The horizontal momentum and the vertical momentum are both conserved.

EXPLANATION :

Before coming into any conclusion, first we have to understand the law of conservation of momentum.

As per the law of conservation of momentum, the total linear as well as angular momentum of an isolated system is always conserved . The law of conservation of energy is a universal fact.

Hence, during any type of collision, the total momentum is always conserved.

Hence, the total horizontal momentum as well as total vertical momentum are always conserved during both elastic as well as inelastic collision.
