Puck 1 (0.5 kg) travels with velocity 80 m/s to the right when it collides with puck 2 (2 kg) which is initially at rest. after the collision, puck 1 moves with a velocity of -16 m/s. assume that no external forces are present and therefore the momentum for the system of pucks is conserved. what is the final velocity (in m/s) of puck 2 after the collision?

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.

does anyone know or what?
