A74 kg window cleaner uses a 15 kg ladder that is 6.7 m long. He places one end on the ground 3.0m from a wall, rests the upper end against a cracked window, and climbs the ladder. He is 3.5 m up along the ladder when the window breaks. Neglect friction between the ladder and window and assume that the base of the ladder does not slip. When the window is on the verge of breaking, what are (a) the magnitude of the force on the window from the ladder, (b) the magnitude of the force on the ladder from the ground, and (c) the angle (relative to the horizontal) of that force on the ladder? (a) Number 226 Units (b) Number 73.1 Units (c) Number 90 Units (degrees)

Concept explainers

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.

Question

I need help in part B and C please

A74 kg window cleaner uses a 15 kg ladder that is 6.7 m long. He places one end on the ground 3.0 m from a wall, rests the upper end
against a cracked window, and climbs the ladder. He is 3.5 m up along the ladder when the window breaks. Neglect friction between
the ladder and window and assume that the base of the ladder does not slip. When the window is on the verge of breaking, what are (a)
the magnitude of the force on the window from the ladder, (b) the magnitude of the force on the ladder from the ground, and (c) the
angle (relative to the horizontal) of that force on the ladder?
