Answer:

0.6m/s

Explanation:

Totally inelastic collision

m₁v₁ + m₂v₂ = ( m₁ + m₂)v(final)

Where v (v₁ and v₂) is the initial velocity of the objects

v(final) is the  final velocity of the objects stuck together

Toy car a , m₁ = 3kg, v₁ = 1m/s

Toy car b , m₂ = 2kg, v₂ = 0m/s

m₁v₁ + m₂v₂ = ( m₁ + m₂)v(final)

3(1) + 2(0) = (3 + 2) v(final)

3 = 5 v(final)

v(final) = 0.6m/s
