A 14.0-m uniform ladder weighing 480 N rests against a frictionless wall. The ladder makes a 57.0° angle with the horizontal. (a) Find the horizontal and vertical forces the ground exerts on the base of the ladder when an 850-N firefighter has climbed 4.10 m along the ladder from the bottom.what is the magnitude of the horizontal force in newtons and what is its direction? what is the magnitude of the vertical force in newtons and what is its direction? (b) If the ladder is just on the verge of slipping when the firefighter is 9.30 m from the bottom, what is the coefficient of static friction between ladder and ground?

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.
