Summarize the characteristics of the scoring criteria on the AP analysis essay rubric. (50pt)

Each of the three AP English Language and Composition essays equals one-third of the total essay score, and the entire essay (free-response) section equals 55% of the total exam score.

Each essay is read by experienced, well-trained high school AP teachers or college professors. The essay is given a holistic score from 1 to 9. (A score of 0 is recorded for a student who writes completely off the topic-for example, "Why I think this test is a waste of money." A student who doesn't even attempt an essay, who leaves a blank page, will receive the equivalent of a 0 score, but it is noted as a dash [-] on the reader's scoring sheet.) The reader assigns a score based on the essay's merits as a whole, on what the essay does well; the readers don't simply count errors. Although each essay topic has its own scoring rubric (or guide) based on that topic's specific information, a general scoring guide for rhetorical analysis and argumentation essays follows. Notice that, on the whole, essay-scoring guides encompass four essential points; AP readers want your essay to be (1) on topic, (2) well organized, (3) thoroughly developed, and (4) correct in mechanics and sophisticated in style.

ek = (m·v2) / 2

v - velocity of system after the collision

m = m1 + m2

ek = (m1 + m2) ·v2/2

ek = (200 + 250) ·2,32/2 = 450·5,29/2 = 1190,25 j
