Querido Fisicos de SWMHS,
I've uploaded the solutions to the HW up to Lesson 7. Please complete Lesson 7 HW by latest Thursday and be ready to ask questions about the lesson and the HW. Part c of 7.4 could be challenging. There are aspects of trigonometry, Newton's First and Second Law, and some mathematical manipulation dealing with components of the force all in one problem so just take your time if you get stuck. The key to good problem solving is to start by reasoning based on the fundamental concepts i.e. when the object is moving at a constant velocity the forces exerted on the object are balanced. From there move towards the more abstract which are mathematical expressions. Starting out looking for a formula is something that lots of people do and sometimes end up successful but lots of times they are not. Be aware of your own thinking process when you are problem solving. Try it the way I suggested and try it looking for a formula first. For each, rate your frequency of success, and on a scale of 1 to 5 with 1 being least confident, how confident you are of your answer. Figure out when it is ok for you to take the short cut and when it is not. Email me if you have questions or if you want hints. Buena Suerte! Y por los que quieren practicar Espanol se puedo mandar estos mensajes en Espanol tambien.
Sinceramente,
Tu profe L

Dear Physicists of SWMHS, I've uploaded more files in the reference folder. Keep these documents handy as they may be of use to you in the future. Use it as if you would use a manual or a textbook. I also uploaded a document called LabL2Comments.doc. Just click on the Dynamics link below. Take advantage of this opportunity to learn and read the document. You may ask me questions either in class or via email.

Sincerely,
Ms. Lagunzad

Dear Physicists of SWMHS, If you are reading this, it means you were looking for the solutions to the HW to prepare you for the quiz and was curious enough to see more than what you were instructed to see. I would like to encourage this behavior and thus I will reward you 1 point extra credit if you send me an email at lindal@eden.rutgers.edu telling me your name and a question you have about any topic in physics. You will recieve 2 extra credit points if you printout and complete the document DynL4Handout.doc and hand it in by Wednesday, Dec 10th. When you download this document, insert the answer to the question below in either the header or the footer and you will recieve another point. It must be typed so that I can distinguish it from the one I provided/will provide in class. This offer ends on Wednesday, Dec 10th. Congratulations for being curious. Those who snooze will lose. MUAHAHAHA

Sincerely, Ms. Lagunzad

P.S. This is a secret message intended only for curious students, and not those who have curious friends and heard the word on the grapevine. This offer is not a joke. If you have any questions about this send me an email.

True or False: There is always a force pointing in the direction that the object is moving.
