*Alternative or extra credit if you solve both: 7.6 using conservation laws: R=.1, m=0.2, M=4, alpha=12 degrees. Assume that the hoop starts from rest at a hight of 0.4 as measured from its center of mass to the horizontal surface. Find the speed of the hoop when its center of mass is at 0.2 from the horizontal surface. The inclined plane also started from rest.

Syllabus

The objectives:

• To introduce the student to the laws of physics and their applications to a variety of macroscopic problems.
• To teach the student how to read and write physical phenomena by means of equations.
• To familiarized students with approaches and techniques of physics useful in other sciences and technology.
• To enhance students conceptual understanding of physics by an extensive use of class demonstrations and/or class activities.

Attendance Policy

Students are expected to be present at each schedule class. Students who are absent for reasons of illness, death in family, etc. should inform their instructors as soon as possible. Faculty are under no obligation to make special provisions for students absent for capricious reasons.

Course Requirements

Students are required to attend classes, to do homework, to take tests.

Notes:

• Late homework has a penalty of 10% off per day (Saturdays and Sundays or other holidays do not count). In your late homework you must write the date when you hand in.
• If you miss class for health reasons you must have a doctor’s note.
• If you miss a quiz you will not be able to make it up. If you have a valid excuse the quiz you missed will not count toward your grade, but you must still hand in the homework.
• Academic Honesty Policy (from Student Handbook): cheating, falsification, plagiarism and facilitating academic dishonesty is penalized with an F for first time offenders.

· Withdrawal from a course after Mid-Semester is considered exceptional and includes a mark stating whether the student was passing or failing the course.
