Question

pplz need the explanation for the answer​

Answer 1

Answer:

Well here if we consider the system to be the ball and the other ball together, then their forces during collision will act as action reaction pair cancelling each other's effects.

So, the momentum here along the line of motion can be conserved.

Let, us consider the direction of motion of the first ball be positive.

So, initial momentum = 5(3) + 3(-2) = 9 kg m/s

Final momentum = 5(0) + 3(v)

V = 9/3 = 3 m/s

So, the second body will then move with a velocity of 3 m/s along the direction of the initial motion of the first ball.
