m1 ≈ 2 kg
u1 ≈ 10
v1 ≈ 1
m2 ≈ 5
u2 ≈ 0
v2 ≈ ?
according to the law
m1u1+m2u2 ≈ m1v1+m2v2
2 × 10+5 × 0 ≈ 2 × 1 + 5 × v2
20+0 ≈ 2+5v2
20 ≈ 2+5v2
20-2 ≈5v2
18 ≈5v2
18/5 ≈ v2
3.6 ≈ v2

Answer:
mass of 1 body=5kg
velocity os 1 body= 10m/s
mass of 2 body=20kg
velocity of 2 body=?
using fourmala
velocity of 2=mass of 1*velocity of 1/mass of 2
velocity of 2=5*10/20
velocity of 2=2.5m/s
