A small box of mass 4.1kg is sitting on a board of mass 1kg and length 1.1m(Figure 1). The board rests on a frictionless horizontal surface. The coefficient of static friction between the board and the box is 0.54. The coefficient of kinetic friction between the board and the box is, as usual, less than 0.54. Throughout the problem, use 9.8m/s^2 for the magnitude of the acceleration due to gravity. In the hints, use Fr for the magnitude of the friction force between the board and the box. Find Fmin, the constant force with the least magnitude that must be applied to the board in order to pull the board out from under the the box (which will then fall off of the opposite end of the board).

Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.

![A small box of mass 4.1kg is sitting on a board of mass 1kg and
length 1.1m(Figure 1). The board rests on a frictionless horizontal
surface. The coefficient of static friction between the board and
the box is 0.54. The coefficient of kinetic friction between the
board and the box is, as usual, less than 0.54.
Throughout the problem, use 9.8m/s^2 for the magnitude of the
acceleration due to gravity. In the hints, use Fr for the magnitude
of the friction force between the board and the box.
