48. This problem involves both mechanical energy conservation UKK i =+ 12 , where U i = 60 J, and momentum conservation 0 11 2 2 mv G G where m 2 = 2 m 1 . From the second equation, we find | | | | G G vv 2 = which in turn implies (since = || G and likewise for v 2 ) Km v m v m v K 1 2 22 2 2 2 1 2 1 2 1 2 1 2 2 == F H G
