REMINDER TEST AND READING GUIDE DUE ON THURSDAY

Answers to problems 2-4: 2a. 48.9m 3a. -6.2m/s/s b. 18m 4a. 765m

Today all we did was review and continue working on our " Acceleratin' Experiences (problems solving)" packet. So in order to solve these problems what we have to do first is label all the number in the problems in order to see which equation from page two we might be able to use. So in number 6 we have bottle rocket leaving from the ground at 0 m/s ( the starting velocity), then the problem give us 43.0 m/s as its final velocity. the time it took to do this was .6th of a second. next we have to make our VT graph and the LMD picture thinger. the Vt graph should look somewhat like the following:

After the graph and LMD are done we can work on the problems. For part a you use the acceleration formula found on the second page to get a= 71.67m/s/s. For part b you need to find the displacement which means you have to find the area of the triangle. the end result should be 12.9m.
