## PHY 2049 - Physics 2 with Calculus - Fall 2015

## Homework Assignments

The homework problems in the WileyPlus system are due weekly
on **Monday at 10:00pm**.
**No exceptions allowed**. The due dates for all HW
assignments are indicated on the schedule
page, and the problems are listed below. Since the WileyPlus
server might have problems occasionally, be sure to start the
assignments early and turn in your answers steadily, rather than all on
the last day. Answers can be entered individually.

Most answers are numerical, and need to be within a certain
tolerance **(2%)**
of the correct answer. Use three significant digits to enter your
answer; do not round off intermediate calculations. You get an instant
feedback as to whether the answer is correct or not. You will have up
to 5 attempts to get the correct answer. Solutions will become
available right after the due date/time.

## Additional homework

Doing additional homework problems beyond those formally
assigned is a critical part of getting proficient in physics and
succeeding in the course. We advise you to do 5-10 **extra**
problems per chapter, randomly picked from the beginning to the end of
the block of problems at the end of each chapter.

Pick odd-numbered problems---they have answers at the end of the
hardcopy textbook and in the WileyPlus on-line textbook to check
yourself, and gain confidence as you build your skills. Moreover,
select problems marked "SSM" have complete, worked out
solutions in the on-line textbook. We caution you to refer to these
sparingly, only after you've struggled with the problem and tried to
get the solution on your own first. It's easy to fool yourself into
thinking you understand and will be able to recreate the steps of a
problem by just following along. That simply does not work.

As a rule of thumb, you
should become comfortable solving two-point problems in less than 5 min
and three-point problems in less than 10 min. Remember: on the exams,
you will have on average about 5 min per problem of varying degrees of
difficulty.
