Dao 10/27

Today we continued working on Relative Motion.

First, we turned in HAC check sheet and the blue sheet (the blue paper that Mrs. Coat-Haan gave us at the beginning of the year). And then we check homework from page 84, number 47 – 57.

While we checking the homework, Mrs. Coat-Haan said “you guys seem relax before the test, and the exam on Tuesday”. It was a reminder because we were talking too much. Then she rode on her chair around the class to answer the questions on the homework and on the pair check.

She showed us how to do number 57, 56, 53, and 51. She showed us do number 56 and 57 using RθXY

Remember: RθXY is where you add two vector using the 2 equations x = Rcosθ and y = Rsinθ to get the x and y components, then add them up to get the resultant in vector notation form.

Then we finished up the pair check with 2 questions that was assigned on Thursday.  We turned the pair check in as soon as we finished it.

Homework is to finish both the test review and the quarter exam review, and study for the test on Friday.

Reminder: on the quarter exam review number 72, 73, and 80. Because they are really hard, Mrs.Coat-Haan will not take off point if you don’t have an answer. Under 1 condition, you have to have the sketch and the given data.

The Honor Review schedule: Thursday – Mrs.Grote in room 270, Friday – Mrs. Coat-Haan in room 266

I don’t know what is the content question for today was, so I don’t have an answer for that.
