Answer:
velocity = 10 m/sec in the same direction as the first body did
Explanation:
The momentum of the body can be calculated as follows:
momentum = mass * velocity
For the first body, we have:
mass = 5 kg
velocity = 2 m/sec
momentum = mass * velocity
momentum = 5 * 2 = 10 kg.m/sec
We know that this momentum is transferred completely to the second body
For the second bode, we have:
momentum = 10 Kg.m/sec
mass = 1 kg
momentum = mass * velocity
10 = 1 * velocity
velocity = 10/1
velocity = 10 m/sec
Finally, we should get the direction of the motion:
Both the velocity of the first and second bodies have positive values. Therefore, the second body is moving in the same direction as the first body did.
Hope this helps :)

Step-by-step explanation:
The order in which the two players will be selected from the 8 trying players is not important. The most important thing is to have the two players.
Therefore, this is a question of combination.
The number of groups = 8C2 = 8!/[2!*(8-2)!] = (8*7*6*5*4*3*2*1)/[(2*1)*(6*5*4*3*2*1)] = 28 groups
