Answer:
Explanation:
We shall apply law of conservation of momentum at the time of collision
Momentum before collision of both the pins = 1.8 x 3.6 + 0 = 6.48 kg m/s
Momentum after the collision of both the pins = 1.8 x .54 + 1.8 x v where v is velocity of second pin
So , according to law
6.48 = 1.8 x .54 + 1.8 x v
6.48 = .972 + 1.8 x v
v = 3.06 m /s to the right .
