Explanation:
It is given that,
Mass of puck 1,
Mass of puck 2,
Initial speed of puck 1,
Initial speed of puck 2,
After the collision, the speed of puck 1,
Let is the final velocity (in m/s) of puck 2 after the collision. Using the conservation of momentum as :
So, the final velocity of the puck 2 after the collision is 24 m/s. Hence, this is the required solution.
