45. Our notation (and, implicitly, our choice of coordinate system) is as follows: the mass of one piece is m1= m; its velocity is 1ˆ(30m/s)iv=−G; the mass of the second piece is m2=m; its velocity is 2ˆ/s)jvG; and, the mass of the third piece is m3= 3m.(a) Conservation of linear momentum requires ()01122333ˆˆ030i30j3mvm vm vm vmmmv=++¡
