General Physics 001
Tips:
1. You can locate your HW problems in your textbook (at the end of each chapter
under “PROBLEMS”). Please don’t hesitate to check in with me if you have any
difficulties finding the problems.
2. Please, make sure that you are working on the problems assigned.
3. For the full credit for each problem assigned you will need to show all of your steps.
Homework 1
1. Problem #6
Hint: (dimensions on both sides of the equation must be the same)
2. Problem #14
Hint: You can use definition of tan
θ
to find the angle of incline.
3. Problem #24
Hint: First, you need to find that resultant vectors (using the graphical method for adding
vestors):
F

and so on and so forth. After that you need
to compare their magnitudes to find the answer to the question.
4. Problem #34
Hint: Find the x and y components of each given vector (using the method for finding
vector components from Chapter 1) and compere their magnitudes.
5. Problem # 56
Hint: Since east and north direction are perpendicular to each other, you can find the
magnitude of vector B from a definition of tan
θ
. After that you can find the magnitude of
the resultant vector with the help of Pythagorean theorem.
