SolutionApplying conservation of momentum formuls we haveInitial momentum of the system = Final momentum of the system501000kg×5+1001000kg×(-8)=501000+1001000×v0
05×5+0 1×-8=0 15×v0 15v=0 25-0 8v=-0 550 15=-3
66m/s (common velocity)Negative sign shows that velocity will be in the direction of initial direction of 100g ball
