1. A pencil standing upright on its eraser end falls over and lands on a table. As the pencil falls, its eraser does not slip. The following questions refer to the contact force exerted on the pencil by the table. Let the positive x direction be in the direction the pencil falls, and the positive y direction be vertically upward. (a) During the pencil’s fall, is the x component of the contact force positive, negative, or zero? Explain. (b) Is the y component of the contact force greater than, less than, or equal to the weight of the pencil? Explain and labled the problem.
On her way to visit Grandmother, Red Riding Hood sat down to rest and placed her 1.20-kg basket of goodies beside her. A wolf came along, spotted the basket, and began to pull on the handle with a force of 6.40 N at an angle of 25° with respect to vertical. Red was not going to let go easily, so she pulled on the handle with a force of 13.5 N. If the net force on the basket is straight up, at what angle was Red Riding Hood pulling from the vertical?
The whole question did not paste in on my last attempt.

I was given the WRONG answer this morning!
The force that Red applied was 13.5N NOT 12.2 N! Use 13.5 N!
I use this service primarily to check my work.
If the "experts" are using the wrong values, I question if they will use the right mathematical procedures if I really have a challenge!

The book's front cover is facing up. If you slide the book very, very slowly toward the edge of the table (by pushing it horizontally, not by pulling it), it will eventually fall off and land on the floor. We did this experiment in one of our Class Meetings and the result was that the book most likely will end up on the floor with its front cover facing down. Why should this outcome happen? How could you prevent this outcome from happening so the book will end up on the floor with its front cover facing up? Consider changing the book, table, or the sliding procedure. Write down a mathematical model to verify your answers to 1 and 2. Use Newton's laws and conservation methods to to help you write a model that either proves or disproves 1) and 2).
