[tex] \frac{1}{2} \frac{m}{s} [/tex]
[tex]\huge\underline\bold\red{Explaination: }[/tex]
Let the final velocity of 4 kg ball just after collision be v. Since, external force is gravitational which is non - impulsive, hence, linear momentum will be conserved.
Applying linear momentum conservation
[tex]2( - 3) + 4(4) = 2(4) + 4(v)[/tex]
[tex]or \: v \: = \frac{1}{2} metre \: pr \: second[/tex]
Hence, the velocity of 4 kg ball just after collision is 1/2 m/s
