A father (m = 94 kg) and son (m = 48 kg) are standing facing each other on a frozen pond. The son pushes on the father and finds himself moving backward at 3 m/s after they have separated. How fast will the father be moving?


Which equation is used to solve this? Can you set up the problem for me?
Thanks

conservation of linear momentum ...

initial momentum = final momentum

what is the final velocity

I've set up the equation and you can't figure it out?

48(-3)+94 x vf
-50 but what is the vf in this problem. I'm still working at it

-48(-3)/94=1.53 m/s
thx
