A 65kg person throw a 0.045kg snowball forward with a ground speed of 30m/s. A second person, with a mass of 60kg, catches the snowball. Both people on the skate. the first person is initially moving forward with speed of 2.5m/s, and the second person is initially at rest. what are the volocities of the two people after the snowball is exchanged? disregard friction between the skates and the ice

Well, st first we should find initial momentum for the first person represented in the task which definitely must be :

(65+0.045)*2.5
And then we find the final one :
65*x + 0.045*30
Then equate them together :
x=2.48 m/s
So we can get the velocity, which is
is 2.48 m/s
In that way, according to the main rules of conservation of momentum you can easily find the solution for the second person.
