It appealed mostly to workers and some intellectuals, but was a relatively obscure movement before 1848.

This ideology promoted state economic planning, state control of property, and a greater economic equality for the masses. Key supporters include Saint-Simon, Charles Fourier, and Robert Owen.
Twо rаilrоаd cаrs m1 = [m1] kg and m2 = [m2] kg cоllide with each other. Before the collision, m1 is moving to the left with a speed of [v1i] m/s, after the collision it moves to the right with a speed [v1f] m/s. After the collision m2 is moving to the right with a speed of [v2f] m/s. What is the final momentum of m2?
