A 35-kg girl is standing near and to the left of a 43-kg boy on the frictionless surface of a frozen pond. The boy tosses a 0.75 kg ice ball to the girl with a horizontal speed of 6.2 m/s. What are the velocities of the boy and the girl immediately after the girl catches the ball?
I don't know how to approach this
(1) I have mass1 (girl) and mass2 (boy) , so that kind of tells me that I have to use conservation of momentum theorem.
m1v1 + m2v2 = (m1 + m2) v (is this "v" 1 or 2?)
is this ok? if so, what else? I don't know what velocity
