m1=5000kg
u1=4m/s
m2=4500kg
u2=2m/s
v=?
According to law of conservation of momentum-----
m1u1+m2u2=(m1+m2)v
5000×4+4500×2=9500v
29000=9500v
v=29000/9500
v=3.05m/s

m1 = 5000kg, u1 = 4 m/s
m2 = 4500kg, u2 = 2m/s
v = m1u1 + m2u2 / m1 + m2
5000*4+4500*2/5000+4500
20000+9000/9500 = 29000 = 58/19 = 3.0526
