Problem 5.3

Please wait for the animation to completely load.

Consider a 2-kg physics textbook (not drawn to scale) pressed against a wall, which has a coefficient of kinetic friction of μ_k = 0.4 as shown in the animation (position is given in meters and time is given in seconds). Restart. 

1. Draw a free-body diagram for the book, showing all the forces that act.
2. What is the net force on the book?  Include both magnitude and direction in your answer.
3. What is the force of the push represented by the hand?
