Answer:The speed of second toy cart is 4 m/s.

(c) is correct option

Explanation:Given that,Mass of first toy cart = 2 kg

Mass of second toy cart = 6 kg

Speed of first toy cart = 12 m/s

We need to calculate the speed of second toy cartUsing formula of momentumWhere, m₁ = mass of first toy cart

m₂ = mass of second toy cart

v₁ = velocity of first toy cart

v₂ = velocity of second toy cart

Put the value into th formula

Hence, The speed of second toy cart is 4 m/s.(c) is correct option
