You can determine the change of kinetic energy by calculating the work done on the system. That would be force multiplied with distance. However, you only have the distance for the given. Anyway, I've found a similar problem. So, I hope I could still help you in understanding it, even just the concept.
So, in the similar problem that I found, two opposite forces are acting on a block along the frictionless surface. F1 = +80 N and F2 = -30 N.
We get the net force. Then, we find the work which is just kinetic energy in form.
W = KE = F*d
KE = (80 - 30)*(4 - -6)
KE = 500 J
So, if you have the actual values and direction of forces, the same concept applies. I hope I was able to help.
Answer:
Success because production in both of these industries soared.
Explanation:
The first five year plan in China was implemented by Mao Zedong from 1953 to 1957. It was modeled after the Soviet's five year plans, and the main goal was to increase Chinese industrial output in heavy industries, particularly steel and coal.
The plan, as can be seen in the charts, was a success in this sense. Both coal and steel production increased, and this lead to an improvement of the quality of life of the Chinese population, particularly in urban areas.
However, there were some problems with the plan, especially at the end of its running years. For example, it did not benefit the rural populations as much because it was not focused on agriculture, and food production could not keep pace with coal and steel output. This fact increased the economic differences between the cities and the countryside.

Australia's Head of State is the Queen of Australia, The President is both the head of state and head of government of the United States of America, and Commander-in-Chief of the armed forces
The Head of State is the greatest representative of a State.
The personification of the state's legitimacy and its continuity is in the figure of the Head of State. He is the one who must embody the spirit of the nation for his own people, as well as for the world. For that, the Constitution of each country defines the guidelines that characterize the presence of the Head of State, but, in general, and because he is the highest public representative, he is responsible for maintaining the continuity of the exercise of powers.
The Head of State is a public representative who is present in all forms of government. When it comes to a monarchy, he is the monarch. When it comes to a republic, he is the president. However, in countries where the government is presidential, the Head of State also assumes another role, that is, Head of Government.
