Today in class we had to turn in last night’s homework: Page 73-74 in the lab manual. Mrs. Coats-Haan checked our homework that we did in the book, page 127 1-9. Then we did some more examples of math problems that had to do with Newton’s Second Law on our notes example sheet. Mrs. Coats-Haan then passed out our quarter assessments and explained her grading mistakes while we did a pair check. After we finished our pair check and looking over our exams we turned both back in. Our homework that is due tomorrow is on page 127 in the book, questions 10-17. In our class Mrs. Coats-Haan kept confusing the Jacobs, since they sit right next to each other now.
The question of the day is: If you have several forces acting in multiple directions on an object, how do you determine the object's acceleration?
I think the answer would be to use “FOXY” to add the forces and then apply the new force you just found to the F=ma equation.
