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 cart
Using formula of momentum
[tex]m_{1}v_{1}=m_{2}v_{2}[/tex]
Where, 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
[tex]2\times12=6\times v_{2}[/tex]
[tex]v_{2}=\dfrac{2\times12}{6}[/tex]
[tex]v_{2}=4\ m/s[/tex]
Hence, The speed of second toy cart is 4 m/s.
(c) is correct option
