Answer:
Second Trial satisfy principle of conservation of momentum
Explanation:
Given mass of ball A and ball B
Let mass of ball and
Final velocity of ball
Final velocity of ball
initial velocity of ball
Initial velocity of ball
Momentum after collision
Momentum before collision
Conservation of momentum in a closed system states that, moment before collision should be equal to moment after collision.
Now,
Plugging each trial in this equation we get,
First Trial
momentum before collision moment after collision
Second Trial
moment before collision moment after collision
Third Trial
momentum before collision moment after collision
Fourth Trial
momentum before collision moment after collision
We can see only Trial- 2 shows the conservation of momentum in a closed system.
