Answer:

B

Explanation:

In a two body collision where kinetic energy is conserved , this means the kinetic energy before collision is equal to the kinetic energy after collision.

when kinetic energy is conserved , momentum is also conserved.

m1u1 +m2u2 = m1v1 +m2v2

or

m1u1 +m2u2 = (m1+m2)v

The above equations are for bodies that undergoes elastic and inelastic collisions. It represents their momentum before and after collision which are equal

Before the collusion the two bodies were moving at their velocities that were equal in magnitude but in the opposite direction.

  • After the collision, the total momentum of the bodies that were attracting one another remains constant.
  • The less massive object will gain momentum The type of collision in kinetic energy always conserves the Elastic. Hence if the kinetic energy is conserved then the system must be conserved.

Hence the option B is correct.
