momentum1= 2000
momentum2= 3000
total Momentum=5000
so, total momentum = (M+m)v
5000=2000v
2.5=v
momentum2= 3000
total Momentum=5000
so, total momentum = (M+m)v
5000=2000v
2.5=v

total mass = (M) = m1+m2 = 500+1500 = 2000kg
m1 = 500kg & m2 = 1500kg
v1= 4m/s & v2 = 2m/s
total velocity = V
so, here conservation of momentum is applied
total Mass×total velocity = m1v1+m2v2
2000×V = (500×4)+(1500×2)
2000V = 2000+3000
2000V = 5000
V = 5000/2000
V = 5/2
V = 2.5m/s
