A rubber ball of mass m1= 10kg is moving to the right with speed v1= 10m/s. it collides elastically with another ball of mass m2= 50kg, which is sitting at rest. m2 is larger than m1, what are the speeds of the balls, v1 and v2 after the collision?

Ok then I will start at that point.

Since it only wants recent history I gather then I don't need to go back to far ago. So I should just stick to the most recent events? Or should I start with the korean war? Would it be wise to mention the Korean war briefly if it is important to the current events?

Thanks of the responses. I came up with the country in order to do on the conflict with North Korea. Yeah I could use a tip on researching what about the conflict I should focus on. I got a bit overwhelmed. and I also was lost on how to cite sources into a paper with footnotes...
