Answer:
0.465 kgm/s
Explanation:
Given that
Mass of the cart A, m1 = 450 g
Speed of the cart A, v1 = 0.85 m/s
Mass of the cart B, m2 = 300 g
Speed of the cart B, v2 = 1.12 m/s
Now, using the law of conservation of momentum.
It is worthy of note that our cart B is moving in opposite directions to A
m1v1 + m2v2 =
(450 * 0.85) - (300 * 1.12) =
382.5 - 336 =
46.5 gm/s
If we convert to kg, we have
46.5 / 100 = 0.465 kgm/s
Thus, the total momentum of the system is 0.465 kgm/s
Studying the structure of atoms and its sub-atomic particles is very important so that we could figure out a way on how to use our knowledge on it efficiently. Nuclear energy is one of the most powerful energies that needs to be properly harnessed and with adequate knowledge of the nuclear reactions, we could prevent nuclear disasters.
