Problem 5.1: A 2-kg Physics textbook pressed against a wall does not move
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 static friction of μs = 0.3 and a coefficient of kinetic friction of μk = 0.2 as shown in the animation (position is given in meters and time is given in seconds). Restart.
- Draw a free-body diagram for the book, showing all the forces that act.
- What is the net force on the book? Include both magnitude and direction in your answer.
- What is the minimum force of the push represented by the hand?
- What happens to the motion of the book and to the forces if the push is greater than your answer to (c)?
