Question

Two identical uniform discs roll without slipping on two different surfaces AB and CD (see figure) starting
at A and C with linear speeds v₁ and v₂, respectively, and always remain in contact with the surfaces. If
they reach B and D with the same linear speed and v₁ = 3 m/s, then v₂ in m/s is (g = 10 m/s²)
