At the beginning of class, we turned in pages 73-74 of our handbook which was our homework the night before. Then, we checked our answers for page 127 numbers 1-9. We worked through some problems in class. Next, we were instructed to get out our Presentation Problems sheet to work through examples using Newton’s second law. This included FOXY! Then, Coats-Haan gave the delightful news that numbers 37 and 40 on our quarter exam were graded wrong and that if we initially got the correct answers she would add two bonus points to our second quarter test. Then ,we got our quarter tests back to look at grades and ask questions. She recollected the tests as we started to work diligently on our pairs check. Most groups finished with enough time to start the additional homework which is page 127 numbers 10-17.
Qod answer:
To find the acceleration of the object when you know the multiple forces acting on it, you use FOXY to fins the force and direction. Then, you divide the force by the mass of the object and you have the acceleration. The acceleration is in the same direction as the force.
