## Assignment # 5 – Chapter 6 Problems

Chapter 6 Problems:

3, 7, 8, 14, 16, 19, 20, 23, 27, 31, 35, 39, 40, 51, 63

This assignment will be due next Tuesday.  You can use the extra two days to finish the previous assignment or to get started on this one.

There will be a test covering chapters 4, 5, 6 coming soon so I wanted to keep up the pace.

## Physics 2A Homework Assignment #4

Chapter 4:
17, 37

Chapter 5:
1, 3, 6, 8, 13, 15, 16, 24, 25, 33, 37, 41

Chapter four is mostly conceptual and introduces Newton’s Laws. Chapter 5 goes into applications. A few of these problems are challenging. Get started on these and come with questions on Thursday/Tuesday!

This assignment will be collected on Thursday, you have an extra two days to work on it.

## Assignment # 2 Solutions

Here are the solutions for assignment #2. Got them on the computer…. so they look clean. Not sure if I’ll do that next time, might just scan them after writing them out by hand.

There are thumbnails of the images on this page, you can click on them to enlarge the images.

It turns out #35 was probably the hardest problem since the second part involved a quadratic equation. That’s something you should be able to do though. It most likely requires a calculator.

## Note about #30 on Assignment #2

For the speed skater problem in Chapter 2, the same situation that you sketched for the first assignment, the answer is not -2.0 m/s^2.  It seems like that might be the answer, but if it’s what you get, check your work and see if you’re using the right equations!

## Physics 2A Homework Assignment #3

Chapter 3 (problems):

1, 5, 6, 9, 14, 16, 21, 24, 27, 30, 35, 40, 53, 67

The difficulty of these problems varies.

You should really get started on this assignment as soon as possible after you have gone through the second assignment since chapter 3 will be included on the first test.

Let me know if you have questions.

Also, I thought I would include a couple of extra credit questions – they’ll be worth one point each.  The hw assignments are each 10 points.

## Physics 2A Homework Assignment #1

Chapter 1:
2, 5, 8, 9, 15, 20, 26, 29 31, 37, 57, 61

Look at the directions for 37 carefully!
